Nintendo is a 132 year old company (111 at the time this happened), with a "war chest" of $10 billion. They've been successful for far longer than Microsoft have existed.
I don't know what Nintendo would get out of being acquired, and I'm not certain that Microsoft would be able to put together a convincing acquisition deal.
