Now, the ball is in AMD's court; AMD has had a year now since they launched the 5870 & 5970 and has no excuse in my opinion not to build single-chip GPUs that can outperform the GTX 580, but if they couldn't, that'll definitely mean that 2011 is going to be nVidia's year, especially that the GTX 560 & GTX 570 should be on the way
those 500 series estimates look well possible from their currant lineup, at least specs and speed wise.
GTX570 will be GF110 with near GTX480 performance, should be considerably less power consumption too.
GTX560 is the fully enabled and clocked up GF104 we've been waiting for.
GTS550 is also a fully enabled GF106, and clocked up, giving it considerably more performance IMO, given at the moment it lacks 50% of its ROPS and memory bandwidth.
