Not to nitpick, but you\'d be surprised what is technically possible and what not. As I said, the PS2 supports resolutions up to 1280x1024 fine and that isn\'t at 30Hz or something mind you. Of course, such a high resolution will come at a tradeoff (in this case larger framebuffers) - but then again, such high resolutions were never intended given that the majority of the world doesn\'t play on HDTV setups (and certainly not in 1999/2000).
There are examples of games that internally run a very high resolution (Baulders Gate is a great example) but downsample it in favour of better image quality at the intended resolution. It surely will be very interesting which tradeoffs we\'ll see in the future in games.
BTW; One thing about this that I do find very amusing is that the following comment
No way no how can the PS2 render stuff in 1080i @ 60fps in realtime so it\'s being upscaled internally
would have surrounded even the claim that GT4 would do 480p (or any native progressive signal for that matter) - it being the benchmark on PS2 as far as graphics/gameplay go. Even I doubted the news on this when I found out and am quite surprised indeed. Quite incredible how far the PS2 has come since its launch.
