PS3 + PS3, simply because those games are hardcore and Nintendo only gets junk or simple spin off games from Square Enix... or remakes. But you honestly don't expect an exclusive KH3 on the WII now don't you? If that will happen, it would be serious world news.
HAHAHAHAHAHAHAHA!!! KH....hardcore? Where was I when they announced this? KH isn't hardcore at all. And it won't be world news to most people 'cause they knew it was coming. Maybe world news to the Sony fanboys, though >_> How about you stop being a little girl and get along with facts?
Edit: The PS2 was a non-hardcore game system, FYI.
