The GPU is the only thing that seems like more than developers have hinted at to me over the last year. It could be a smart move though, if the smaller process and wafer size reduces heat and power requirements.
Sidenote: any rumor of current specs that lists anything other than x86 is extremely suspect. Anything mentioning non-AMD parts is also suspect. I'm sure they're going back and forth like crazy over cost right now, and that might mean the memory numbers won't be finalized til just before announcement. Which I've also heard is coming sooner than most people think, though that tidbit was based on a totally off the cuff exchange.
Geoff said that next gen games will be shown during the vgas. Any idea if around that time we here something from sony or ms?
