i heard they want to release something on that day but it wasn't Fermi based GeForce. it was something else
At this point, we know very little. No credible rumors have come out telling us how smoothly the process is going. Oct. 31st though is overly optimistic even for the best case unfortunately. I'd be looking for a few cards out, maybe only to reviewers, before the new year. Hopefully in larger amounts soon after. I think the best case is a semi paper launch in November. Worst case? Anywhere from Q1-Q2 of next year.
