Will SSB confirm the New Challenge: Rayman?

Middle of month after I saw a exclusive picture of Super Smash Bros. upcoming games which appeared Rayman as trophy.
I'm sure that will SSB upcoming games confirm the all-new challenge being a third-party: Rayman?
No, I'm not sure. It's too that i think it must 50 fighters confirmed from SSB for 3DS/Wii U before a game developer will confirm in August 12(however Tuesday).
Note: I want to confirm Wonder Red, Ballon Fight, Mewtwo and Popeye from SSB upcoming games! LOL
And you, do you think that new challenge?
