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

[Nedjo]

I've learned that the new GT200 55nm will come maybe in the end of Q3, but probably in the beginning of Q4. Either way it isn't very far away

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?!
