I feel like I should point some things out that may or may not point to Rayman's playability. Firstly, this wouldn't be the first time Nintendo had to cover up something one of their reps said. Back before E3,
this happened. Basically, someone from France said that SSB4 would use the NFC technology, Nintendo later clamed that there was nothing to announce. We later learned about Amiibo, and that SSB4 would be compatible.
Also, as for the fact that there are two trophies, I may have an explanation (assuming Rayman is playable). Take a look at this trailer (skip to 57 seconds and pause it): Notice that Wii Fit Trainer trophy in the middle? It's different from her artwork. But if you look to the left, you see a trophy of her that matches her artwork. And, if you look a little to the right of the middle one, you find another one of her in a different pose. This suggests that playable characters have multiple trophies. Hence, Rayman would have multiple trophies.
I'm not saying this confirms Rayman, but it's food for thought.
