ATI RV740 and RV790 in preparation?

ATI quietly preparing a reply to GTX285 and GTX295 who themselves were a response to the 4870 X2 which was first place for performance over several months.
We learn that stamped samples RV740 and RV790 would be outstanding, and yet it is only a simple die shrink to 40 nm, thereby understand pasted a copy but with a more detailed engraving and can be frequency revised upwards.
ATI will be like with nVidia GT200b, with the key to reduced consumption and increased frequency minimal but nothing transcendent.
These chips probably will replace the current HD 4850 and 4870 pending the release of the RV870 which will bring a new batch of much consequence. The launch date is set for March (who said Cebit).
