I'm not quite sure if it was confirmed or just a rumour as my friend was telling me about it, but there are supposedly plans to remake Silent Hill on the PS3. But they want to change the characters to those in the upcoming movie, which would mean they would have to remake at least 3 as well as the storyline would be all messed up..
And Tetsuya Nomura has mentioned that a FF7 remake WILL be done on PS3, but not until some current projects are finished.
