Might want to wait for the white ceramic version of the PS3 if are leaning that way.

Personally unless you want blueray player I would go with the x360 until there is a game you really want.
The number of 360's out there dwarf the number of PS3 so its likely unless a game maker has a hate on for M$ or Sony doles out the cash, that the 360 will continue to have a descent game selection.
