That would be an example, and an awesome one. If only

.
Yeah exactly. Same for the West too, even if we haven't seen any examples yet. Sony and Microsoft will be playing moneyhat to secure exclusives, and I think it's obvious third parties are trending towards Xbone and PS4 far over the Wii U. It's like the PS3 and 360 generation. Third parties will still fund and publish their own games, but Microsoft/Sony will be throwing money at them to waver licensing fees or whatever, arranging special promotions, etc, for timed or permanent exclusivity.
I think it would be very unusual to see that kind of behaviour on the Wii U because the vibe I'm getting is that third parties are shitty with hardware performance, and shitty with software sales. But that doesn't rule out Nintendo swooping in to pick up games that have otherwise been abandoned and publishing them off their own back.
I don't want to imply I actually know of any shit like that happening, mind you. Bayonetta 2 could be a once off. But it does seem like a more believable strategy for Nintendo to employ in securing exclusives. Because they sure as hell aren't going to come from publishers.
This would actually make Beyond Good & Evil 2 a great fit, and I agree with Ani that the series would probably do pretty decently on a Nintendo platform, especially if it had a Nintendo published stamp on it. But I think if BG&E2 ever actually happens Ubi will retain control and get it on as many platforms as possible.
