Someoen asked about the AF on the Rollei 6008AF. I had one, and the autofocusing was OK, but only OK. It was faster than the Contax 645 (I had one of those too), but not as accurate (it would hunt more). I remember reading, however, that the later versions of the 6008AF (I had one of the very early ones) were significantly better in terms of accuracy. In short, the 6008AF's autofocus was OK. Given that I don't shoot sports or wildlife, it was fine for me.
But, even assuming you're using the existign Schneider AF lenses on this new camera, there's no reason to assume that AF will be the same; presumably, a better AF drive and focusing algorithims in the camera itself would help.
For those of you who've seen the new camera: what's the deal with what you see in the finder in relation to the back's position? I.e., is it a square viewing area with horizontal and vertical 6x4.5 etchings on the screen? It would be really nice if the appropriate vertical or horizontal markings or "blades" popped up in the viewfinder when the orientation was changed -- wasn't there a Fuji camera that did this? You;d think it'd be even easier to do that these days, given that you could just do it electronically in the viewfinder.
