Interesting that a former Sony fan (boy is deliberately left out here) has almost persuaded me to go 360.
I forgot about Too Human and Alan Wake, absolutely interesting titles. Fable 1 was pretty bad, but 2 seems to be much improved.
Like I said, MGS4 doesn't interest me as much since the Konami "bribing" and because 90 minute cut scenes are absolutely ridiculous. Nice for the real fans, but I'm a hard working man and it would take me way too much time.
So unless RE5 is significantly better on PS3 I think I'll go 360 (once they've improved their hardware).
