I'm with you apart from the ps2 level graphics. I think it needs to be 720p minimum, in fact I'd happily stay at that but I want all the physics and environmental effects turned up to 11.
I mainly get PC versions because their cheaper, any graphical improvement doesn't matter to me too much. Smoother framerates are nice of course.
I'll only be intrested in the next gen when I hear of proper gameplay additions, that usually takes a while. Hearing of high resolutions and better looking whatever else leaves me cold. I was happy with PS2 level graphics, the main thing that ages those era games now is the often poor physics for me.
