Feeling a bit like a character out of Star Wars, the force is certainly strong (to pull me over to the dark side of NAS). But truth be told, the D300 is a fantastic camera. While I find the D700 specs to be intriguing (I like the built in Live View level and the fact that you don't loose frame rate speed when shooting in 14 bit), the specs are hardly groundbreaking IMHO (not like they were when comparing the D80/D200 against the new D3/D300).
For those of us who aspire to produce tack sharp images yielding the highest possible resolution, the D300 delivers admirably. And let's face it, any large sensor gains can easily be negated with bad technique and technical ineptitude. I am actually surprised at how little this announcement is actually fazing me. When the D300 came out--I just had to have it. Who could resist the seductive pull of a new 51-point focus system, an improved CMOS sensor, better color accuracy, 14-bit raw capability, Live View and so much more.
And now that Nikon has introduced firmware to address the dead battery issue, detractors should be few and far between (especially given the low price point). That's not to say that there won't be droves of people flocking to purchase the D700. And the D700 will produce breathtaking images--in much the same way that the D300 and D3 (and even the D80 and D200) are capable of doing now. It's all about incremental technical improvement--which may be mutually exclusive to the actual talent of the photographer and their ability to take advantage of any model to model innovation. And like I have pointed out in other posts, I viewed the D300/D3 line as a revolution, whereas the D700 is more of an evolution.
I have no doubt that I'll be migrating to an FX camera sometime in the next two years. Maybe when Nikon introduces an updated version of the 70-200? My guess, is that it'll be the D800 or D900 (whatever is the next version after the D700). For now, I will humbly and loyally stick with my tried and true D300. When the day comes where the new specs wow me (like they did with the D300), I'll be first in line--rest assured. Anything else is just the NAS force trying to pull me over to the dark side.
