I should point out this happens all the time already - most of the promotional shots for *all* videogames, especially for ad videos, are being rendered on PC, even when there's not a PC version coming out. - Take a look at Arkham Asylum for a good example of this. There are tons of screenshots where the textures and lines are just *perfect*. It doesn't matter that the console version has aliasing, it doesn't matter that in practice most people can't run it at those settings - because the promo shots can be done on dev workstations, and you can't see framerate in a screenshot :P
