Didn't Insomniac say after they announced that R&C was going to be 60fps, that henceforth all their games were going to be 60fps? They may come back on it, but as it stands, that's the best we've got on the subject (i.e. the horse's mouth), so for now I'm going to assume that's what it will be. However, I do think they don't really need it. Maybe in multi-player, but to me, framerate was more than smooth enough.
I thought Resistance was absolute class and online support is terrific, though I must say that I've fallen out of love with its graphics of late in multiplayer. But Resistance is one of those rare games I finished, and I'm really looking forward to online coop, and if they can improve the lighting, then together with proper texture streaming (none of that at all in part 1) it could make a huge difference. As everything else in the game is pure class, at least to me, I'm definitely looking forward to it. And having real locations in the US could be a nice boon, too.
