if we're going by the criteria of formerly multiplatform, now exclusive, that rules out rodea the sky soldier... unless they're having the 3ds version canceled. it also rules out mega man legends 3, unless that was a title also in development for another platform.
lily bergamo would unfortunately also be unlikely if it was actually reworked into another title.
i also feel that these games would have to be japanese, although a big part of me wants them to have seen development on beyond good & evil 2 through- which would fit with 'not necessarily violent', but it would also garner a pretty big response like bayonetta, so it's probably not happening. plus, in general i don't see it. ubisoft has been quiet about the game, but they haven't denied it actually being a thing that will happen. they're also a pretty big publisher, who wouldn't need help releasing a game (something valhalla and platinum required after their original publishing deals fell through). furthermore, ancel's team at montpellier's been working more on the ubi framework stuff, in addition to rayman origins and rayman legends over the last couple of years. and if nintendo wasn't keen enough to jump in and secure rayman legends as an exclusive to the wii u, i don't think they're going to risk more on a far more ambitious and risky title.
cry on does make sense, given that it was mistwalker and nintendo's recent history with them. i just wonder how far back nintendo's going to dig for these titles. cry on was 2008's news, and ni-oh was 2004? bayonetta 2 and devil's third both faced 'the troubles' right around the same time in 2011 or 2012, when it sounds like nintendo came in and helped out.
