Well (some) people were expecting the GTX680 would be twice as fast as the GTX580.
The price and price/performance of this GTX680 GK104 will be a cue on when the GK100/110 will be released - if NVIDIA try to significantly undercut AMD it will mean a faster card will arrive sooner than later, otherwise those Q3 and later projections will be more probable.
Q3 and later?
Ain't that late enough to considered a refresh?
