55nm GT200 (GT200-400) on the way?

[alexio]

since 55nm process is linear shrink, we'll have 400 mm^2 GPU at bast case (if NVIO2 isn't implemented on die). If NVIO2 is implemented then GPU will be few % bigger! That's still way bigger that RV770's 260 mm^2 so I don't see how NVIDIA can compete with ATI margin vise?!

My prediction is that it will have less redundany to make it smaller than 55nm alone could. I've stated before that Nvidia may go all out and release a chip with more active components (and the same or a little more transistors), but this will hurt them financially in the short run. In the long run their image may be more important.
