Apparently, PS3 can't upscale. At all.
If you have an HDTV that supports 1080i but not 720p, you will end up playing 720p games in 480p, because it can't upscale them to 1080i.
Also, a more minor problem with this is that it can't upscale PS1/PS2 games either, so you're stuck with 480i for PS1 and 480p for PS2.
Didn't see this posted anywhere, and I thought it might be good info to know if you're planning on getting a PS3 and have a TV that only supports 1080i.
