I just found out that live view will increase the shutter count every time it's activated even though a picture may not have been taken. Sure enough that explains why my D800 EXIF data shows 700 pictures taken but the number of actual images based on file number is only 359. I shoot most of my landscapes in live view and manual focus for image sharpness. The penalty is that each actual picture counts as two shutter actuations. If you shoot a movie, it counts as a shutter click, but if you leave it in live view, starting and stopping movies does NOT affect shutter count.
The shutter count on all Nikon DSLRs is exactly that. It's a shutter count, not the number of frames.

To add to what the others have said, consider what happens when you use LiveView. Remember that LV uses the imaging sensor, so it has to be unblocked to start LV. When you enable LV, the shutter opens - basically for a 10 minute "exposure." You use the sensor for viewing, focusing, etc. When you release the shutter, the camera turns off the sensor (and probably resets it to change it over from video mode to still mode), closes the shutter, enables the sensor, then the shutter opens for the shutter speed duration, and then closes. Now think about what happens when you shoot movies. You open the shutter once, and the sensor and processor create the movies. When you're done, you close the shutter. Given that the count is of shutter actualtions, I think folks would be upset if it did not count this way.
I wouldn't worry about this. Yes, it's twice as many actuations as you're expecting. But in general if you're using LV, I don't think you're in any kind of high speed frame capture mode. If you're like me you probably aren't even shooting one frame per minute, let alone n per second. Given the design life of the shutter, it's going to take a LONG time to wear it out. By the time you get to 100k, Nikon will probably have an 80mp monster to replace it anyway...

Thus, is there a way to know how many photos we have taken with the newer cameras? I still use my D200 (i.e.no such issue) but am waiting for D800. Is it possible to parameter the camera to have a unique photo number for every photo taken for the entire life of the camera?

If you think you are getting cheated by recording more pictures than you took, it is actually the other way around. I think Live View and movie making put more wear on the camera that single shots using the viewfinder.
Thanks, I should have added that I would like to have this capability not because I feel cheated but only because I'd love to have a simple unique ID for my photos, and also for curiosity (i.e. Know my shooting stats).
There are alternatives, but this is a point I hoped was possible because it seems simple to implement (although the unique ID could be problematic for the pros shooting with two bodies, etc.). There must be reasons I ignore because my first digital camera (Nikon Coolpix 5000, $1500 in 2003, 5 Mg pixels, raw files, etc.) had unique ID for every photo.)
