Not that either situation is likely to happen, but for argument's sake, it would definitely be the Sony option. Like Tor said, Nintendo's been around for over one hundred years. Yes, they had a bad year last year, but you still have to realize it's the first time they've posted a loss in the over three decades since they started making game consoles. They are in absolutely no danger of going third-party any time soon.
Sony, on the other hand, has been bleeding money for awhile. In this hypothetical version of reality where one of these two options happened, the several-billion-dollar lump-sum they could get by selling the Playstation brand and their internal developers would look mighty enticing.
Interesting question.
