There's no way. Rayman just doesn't belong alongside the rest of the roster. He's not iconic, he's not very associated with Nintendo, there's enough 3rd party characters already and they're way more qualified, it's already been said that Sakurai is being very picky about 3rd party characters, and after that bullshit with Rayman Legends, I don't think Ubisoft deserves it. Also, as someone who played the original games, I really despise where the series has gone character design wise. Rayman as he is now is horribly uninteresting. Some might say the same about Mario, and certainly he's a pretty simple character, but Mario is nowhere near as bland and uninteresting as Rayman. The only upside I see is that he's a colorful character aimed at kids and thus doesn't look horribly out of place, but then Snake fit in well enough when he was in, so it's not like that means much. I really hope Rayman isn't in, that would be very disappointing for me.
The only real evidence I can think of in favor of it being true is that supposedly the characters were decided before development started, which might have been before the Rayman delay from Ubisoft.
