RUMOR - Nintendo of Canada employee implies that Rayman is a playable character in Smash Bros. Update: Nintendo issues a statement

Well, it would make sense, because then they'd have Mario, Sonic, Mega Man, Pacman and Rayman. That's kind of most of the biggest old-school mascots out there, and he'd fit in with the rest of the cast pretty well (unlike that dreadful Snake in Brawl).

Then again, considering Ubisoft's support (or lack thereof) of Nintendo's platforms, especially the whole Rayman Legends debacle... it wouldn't make sense. Nintendo don't have to do it to suck up to Ubisoft for games, 'cos see how that worked out for Metal Gear games on Nintendo systems by including Snake in Brawl. Even with Wii's 100m+ install base, they got nothing.
