Eh, don't worry so much about the graphics. If it's what I think it is, it's going to be Vista-based only and will be sucking up six gigs of RAM and you'll probably *need* dual-linked video cards to handle the background requirement of Vista - assuming, of course, that they link the AeroGlass interface into the game somehow, which I'm going to go with because bad developers do things like that. :p
Sorry if I feel like a bloody cynic, but we're in an era where a good game comes out rougly every 2-3 years...just one!
