I'm just waiting for MGS4 to break it's exclusivity...At least release for both systems....or an anouncement that all future MGS games will be released first for the 360. Then there will be no doubt.
EDIT:
If you ask me Wii will just take over the place of Sony over there, or at least the DS, the console market's on the decline over there.
That's probably because they hate 360, they can't afford the ps3 and the Wii isn't delivering fast enough.
