I'm sorry to butt into this conversation without reading the whole thing but:
Ratchet & Clank: Tools of Destruction on PS3 is easily the most graphically impressive title from 2007 on the console in my opinion*. I don't think anything else comes close. If you read about the development of the game, Insomniac said they wanted to create Pixar-quality visuals and I believe they thoroughly achieved that. That was only possible on consoles at the time and it was a case of Insomniac wanting to push the graphical boat out.
They don't do it often... but they can attempt it if they want to.
Aside from that though, I don't give two shits what console my Ratchet games are on. They look fantastic on a big screen but equally I'd love the portability of having a fully fledged game on the go. Just give me more!
*Aside from maybe Drake's Fortune.
