"Does the New D3200 Have Same Resolution as D800/E?"
Would 24 mp on a DX sensor (i.e., D3200) be equivalent to 36 mp on an FX sensor (i.e., D800) considering the (Nikon) DX 1.5x crop factor? Therefore, wouldn't the effective resolution of these two cameras actually be the same in real use? Or do I have this all wrong? Thank you so much for your assistance (or for straightening me out)!

Based on everything I've read over the years there is very little difference between the sensors used in the "pro" cameras and the "consumer" ones. The differences are more about pipeline ASICs and other features in how the sensor is being used.

Do you think that they take the prosumer sensors out into the backyard, hit them with a hammer, and then put them into the less expensive bodies? My guess is that the D3200 will outperform any DX body, todate.

36MP D800 gives a 16MP DX crop. This happens to be the D7000 MP count as well therefore the D7000 and the D800 have nearly equal pixel densities (pixel sizes), and similarly the D3200 has a higher pixel density (smaller pixels than either the D800 or the D7000).
Yes, the crop factor is related provided the pixel sizes are equal. However, the number of pixels is related to the square of the crop factor because crop factor is a linear measure not an area measure. Ratio of number of pixels equals 1.5 times 1.5 which equals 2.25.
FX is 2.25 times DX (9/4ths) because the sensors are 36x24 for FX and 16x24 for DX (36/16 equals 9/4ths equals 2.25). (sensor sizes rounded to the nearest mm, actual ratio comparing diagonals and using exact sensor sizes gives a bit higher than 2.25, hence John's number of 15.3)
Quality of individual pixels may will also vary from generation to generation and camera to camera so - as we all know - comparing pixel count does not predict photo quality.
The D800 still has more pixels so you can get better resolution with a D800 and, for example, a 75mm lens framing a subject as you would get with a D3200 and a 50mm lens framing the same subject. The framing would be the same since the crop factor of 1.5 has been used in selecting the lenses, but the D800 would have 36MP on that image while the D3200 only has 24MP on the same area of view.
If you are shooting distant ducks on a pond, however, you may not be able to fill the frame with either camera and then the D3200 may be able to place "more pixels on the subject" because it has more pixels per angular measure (higher pixel density). That extra "reach" sometimes results in better images and sometimes doesn't depending on other specs for the two sensors and for the two cameras.

The answers so far are all correct except for the first one which may or not be depending on how the actual camera works as a whole. Comparing sensors is not the only predictor of overall performance, but it is the biggest single most significant one. The 24 mpx sensor will likely be very good. It is of a generation that has allowed greater yield in manufacture(the biggest cost variable factor in setting price of silicon chips) and with evolving microlens technology, signal processing(it has the Expeed 3 processor which is state of the current art) so I expect it to be as much of a step up in entry and mid level cameras as the D800 is in pro/semi-pro cameras. Quality of silicon chips, which the sensor is, does not so much depend on cost of manufacturing. It is not like a fine hand wade watch which can cost 1000 times more than a mass produced watch, where craftmenship determines the value added. Design and innovation of chips are the keys and those up front costs per unit drop dramatically as volume goes up. Millions of these sensors are going to be built. The same technology is used in making high end and low end sensors, on the same production equipment, once the design is set, they get cranked out with little difference in costs to manufacture other than yield and square mm of silicon used in the blank wafer. If there is a image quality difference between the D800 in crop mode and the D3200, it mostly will come from intentionally limiting of features to keep product differences between lower cost cameras and middle or higher prices cameras. Based on Nikon's big steps in delivering value and performance in the new releases and a real step ahead of the competition, I have no reason to doubt that for most small camera users, until the mid line cameras are updated, will be the king of the hill for a while in crop cameras in image quality. For those wanting a light, modestly priced camera the D3200 is going to be THE answer for millions of people. Stan St Petersburg Russia

Maybe, the on-board ADC is not going to be worse, making silicon better or worse to hit price points does not really work in reality, so features are engaged or disengaged for price point. The fact is that the formula that started with the D7000, then D5100 and D800 all have similar performance at low ISO and are essentially linear decrease in DR versus 1/log of light. So the main difference in DR versus ISO is directly related to gain added, hence the straight line. Nothing before had this ISO'less sort of performance but all three of these late model sensors have it. It is a winning formula so why not have the 24mpx, or a 16mpx with emphasis on killer AF of the D4, some tweaking of NR handling of the and image processing of the Expeed 3, higher res metering sensor in a pro style body and call it the pro DX model. If it had an integrated grip like the d2 series, I would be all over it. One thing to notice is the gain of the D4 extends further than other cameras even when the DR is below the level of what would be acceptable for most types of pro work. It is an action camera so more gain, and accepting a more restricted DR at 102k or 204k ISO would be an acceptable compromise for action shooters when conditions determine either shooting that high or passing on the shot entirely. A studio photographer would not even try to test the limits because the results would be unacceptable for their clients. So the D7000/ or new 24mpx sensor might be a perfect fit for action customers of the new D400 that has H2 or H3 extended ISO gain. Noise does not suddenly overtake the image with these new series sensors, there is linear progression of noise that aids a photographer in selecting the best compromise with some confidence in the results. Either this or the D400 is delayed because of some new wild technology that never existed before. But I doubt that, the camera is intended for a less esoteric range of subjects where ruggedness, current level of IQ, speed and handling are the key criteria. Few D300 owners cared that the D90 equaled or bettered the IQ of their camera, or the D7000 was better in most criteria. They cared about the handling, build, AF and speed. So all the parts are in the parts bins to make a highly desirable pro grade DX camera that will sell truck loads of cameras. Stan St Petersburg Russia

The mistake in your math is that the FX sensor is 1.5x wider than DX and 1.5x taller, so to calculate the resolution of an FX sensor with the same size pixels as a DX sensor, you need to multiply the DX resolution by 1.5 twice. This is why the D800 crop is ~16MP. 16MP x 1.5 x 1.5 = 36MP
