I ask if YOU know it. Games are not made exclusive just because a company that owns the console also owns it, do you truly think Bayonetta is owned by Nintendo? Even if its not an exclusivity contract, Microsoft did not always own Killer Instinct, and could easily sell it again, specially considering its not doing that well. Also, yes, Mario should go to other consoles, Nintendo's gimmicky consoles only survived because of these exclusives, but they also ruined many games that could have been awesome (latest Star Fox, for example). Nintendo would be much better if they were just game developers.
