Consumer rebadges of old cards (77xx, 78xx) based on the 6000-series VLIW4 arch. coming out first, new 79xx series cards based on totally new architecture coming out Q4'11 or Q1'12.
Also a 7990 "New Zealand" dual gpu coming spring next year.
28nm process and later shrink to 22 or 20 which means less power consumption, potentially smaller cards, more performance per dollar.
Any word on number of Stream Prox?
Nothing besides rumors, expectations are only based on the fact 28nm lithography allows for 30% more transistors.
Biggest news bomb is the fact they are abandoning VLIW based stream architecture and moving onto SIMD instead of VLIW3.

Hoping Nvidia will release their Kepler arch. fast to pressure AMD into an earlier release.
Consumer level GPUs (76-78xx) are slated to arrive much earlier, Q3/4 this year.
Mobility radeon's (laptop) will be among the first
