Stevey: o_O. Half of your comment is unreadable. And how does Linux belong in there? (First, it's going up in use very quickly, and second, it's an OS, not a console.... o_O)
Pudu: Consoles tend to follow the PC market, and as such I'd be surprised if Revolution wasn't dual-core. Then again, Nintendo does have a mind of its' own...
Vudu: Frankly, HD means nothing at the moment. All it means is that the TVs have a higher resolution... Meaning it's clearer looking to you. But it doesn't degrade the graphics quality in terms of effects and things - All the lighting effects and high-end textures will all look the same on 1080p and 480p. And if Revolution's GPU has good anti-aliasing, then frankly, we shouldn't worry about HD anyway. It'll make stuff smoother, not sharper, and that can be much better in a lot of cases.
As for development prices and console prices, at this point I think that we should just wait till TGS and see if Revolution is unveiled, and iff PS3's details are unveiled. If PS3 is above $400, then I think it's safe to say that it'll lose market share.
