I agree with your thoughts on AA, but not with framerate
the 49 number came without info, without settings, withouts models at same time, AA infos
it cames from dev kit a bit different from what ps3 will be (if I remember right, the nvidia in DK have 256 bit mem), so it is very difficult to extend this number to something
any framerate between 40 and 60 fps will become 30 locked fps, if they will have framerate between 70-100 fps, for example, then the game will be 60 fps
but with what settings, how much and how big textures?
We don't know this at this time, one thing is sure, the game will be 30 fps locked or 60
(of course, this is the only thing that we can say)
