You got to be kidding me, right!? And judging by the three smileys, you are.
Actually i wish i was kidding, but I am not. i just cannot believe it myself. Look for yourself. The projected release date is Autumn of 2013 - so almost a full year away.
Also, I have two Zeiss ZF2 lenses I use on my D7000, and I love them. I bought them as full frame lenses in anticipation that someday i would upgrade to the D800 (or maybe the D600) and I would have lenses that would not only cover a FX frame, but would be optically "worthy" of the new camera.
Now I am frankly blown away to find out that even according to Zeiss, these lenses are not even good enough for the D800. Kinda takes the wind out of your sails real fast, eh?
IMO, the main reason for somebody like me to upgrade to the D800 is to be able to push that camera to it's full resolution, it's full capacity. for day to day work, my D7000s are all I need, but I also shoot 4x5 sheet film, so the idea of a really high resolution DLSR appeals to me. It's kinda like buying a brand new Lamborghini - you know the real reason you buy car like that is some day you really do want to see if it can hit 200 mph.
But here and elsewhere I keep reading about people who are disappointed with different lenses on the D800. I suppose it depends on your standards, but again, as with the Lamborghini, why buy it if you don't want to push it to the limit some day? the issue with the D800, IMO, seems to be like buying a brand new Lamborghini and finding out the only roads you can drive it on are old gravel roads at a top speed of 50 mph, and the Germans are still a year away from building new roads that can handle the top speeds of the car.
