Sounds like they're following Intel's lead. the top chip is no longer for enthusiasts but for professional use. (All of Intel's 8-core chips go to server procs) I'm sure they'll release this baby for consumers but most chips will go to workstation cards where $2k - $5k isn't out of the question. 512 bus makes more sense in that case. I think AMD will still go mainstream-ish with their 8000 series. We'll get a performance increase but they'll be under 400 mm^2. I also think that nVidia had the GK100 in the development cycle but didn't want another GF100. Work longer on the development cycle so that the initial release comes off without a hitch. If they had done a release of GK100 it'd be worse than the GTX480 was at release. But I'm sure the GK110 (GTX780?) will be problem free.
