Why does everybody think that hd 7000 is coming out this fall? Just b/c of that BSN article the other day? Neither side is going to bring out a 3rd high end line of cards on 40 nm, and I just don't see how either TSMC or GF are getting them to 28nm in time for BF. I hate to be negative, but I think that 2q 2012 is the most likely release date.
Next gen consoles can't get here quickly enough, maybe once those come out we'll get some new/more demanding games and cards to go with them.
edit: from reading the AMD conference call notes, that just reinforces my thoughts. Both camps like to bring out new processes with low/mid range cards, so maybe we'll have a 5770 or 6670 replacement before year end at least, but don't get too excited about a high end card this year.
