Ok.. personaly I don't care, as I just got 20D and it's wonderful. Here are some "odds" I find about the specs:
1. Full frame in a non 1-D body? They must be joking. I think if it turns out to be real, it will have a 1.3 crop factor sensor
2. DIGIC-II. I think Canon will introduce a new version of it's processor with new pro body (1-D Mark III perhaps?). It's 1,5 year old technology and it still does it's job wonderfuly, Canon will replace this in a near future IMO
3. Quick return half mirror (bla bla).. no cut off with 600 mm f4.0 or shorter.. Now I think every other Canon D-SLR can do this with their mamoth 1200 mm f5.6 - without a cut off. Sounds a bit strange to me.
4. 60 image buffer with a 3fps body? Clearly a joke. What for? 1-D mk. II, which is a 8.3 fps camera has 40 image buffer, Nikon D2Hs, which is 8 fps camera has 50 image buffer.
5. X-sync 1/200 s... It doesn't have onboard flash (it looks like it doesn't). So you have to use external flash, which can be set to high speed sync mode on most of Canon's D-SLR's (if not all, I don't know if it's possible on 300/350D, but I think it is on 350D). And there is not a single word in the speclist about hs x-sync.
Just my thoughts, again, if it turns out to be real, then it's ok. Besides 3500 dolar(euro) camera is not for me.
PS: D200 is just around the corner? People, get use to the fact that Nikon replaced D100 with D70. It lacks some features of D100, but they added some D100 did not have. Just buy D70/s and take picutes, don't wait for D200. And if it's around the corner, in what Nikon segment would it be? 4mpix (2 cams already), 6 mpix (4 cams), 12 mpix (1 cam)?
