I think I'll wait until the PS3 comes out so I can make a good decision between to two.
... actually, I know I'll already want a PS3 because of the games that'll be on it. So really what I'm doing is saving my money for a PS3, and then seeing if the 360 is worth buying with any money I (may or may not) have left
