No, actually it is. 1080p Halo Reach wallpapers are something that are obviously rendered on developer PCs and not the console.
Install limits? What percentage of sales are lost to people letting other people borrow their retail copies? I mean goddamn what are we back to the "don't copy that floppy" age or something?
I don't really understand how the PC version of all could be delayed. DICE being a historically PC developer, it being a more cheap and easy to develop for platform and all. Maybe Sony or Microsoft payed to have it delayed so they could hope to push more consoles for European markets.
Gran Turismo's sales have always been inflated. GT3 only "sold" as many copies as it did because for a long time it was bundled with the PS2.
