According to our dear Charlie, nVIDIA has tapped out GF108:

GF108 is what Nvidia taped out, so its triumphant vaporware GF100 is indeed going to be followed up by a huge wave of GPUs, all of them low end.
Even with somewhat good news, he cant resist to make it look bad:

At this rate, Nvidia will have a full line of parts, in quantity, but not until Q4. Q4 2011, that is.
