The only choice that makes sense is Capcom. They are spiraling right now and their business would be very beneficial to Nintendo. They have a decent legacy on Nintendo Consoles and they would severely hamper the competition if they were exclusive. Not to mention, they are probably the only one out of the big three that would be able to buy them. (Microsoft is not Japanese and Sony is not in a good position to make that type of acquisition financially.)
