3DS version looks weird. I'm just gonna put that out there.
I don't think Mega Man is going to be overpowered. He has a great projectile game, but looking at what I've seen, he'll be somewhat horrific in a game with close quarter combat, and as such may have difficulties landing those key smash attacks. I have a feeling he'll be harder to use than everyone is giving him credit for.
The Villager is what I worry about. He doesn't just block projectiles, he sends them right back. It wouldn't take a fighting game veteran anymore than a hour to get the timing down if they really wanted to. If anything, the Villager is the first character on the banned wagon in a pro tourney. Betting on it now.
Wii Fit Trainer is cool, and I'm expecting great recovery skills from her. Her Final Smash seems similar to Mario's Mario Finale, so I'm gonna take a guess and say she is going to see a lot of use from players.
Other things I wanted to say.
- Yoshi wasn't in the trailers. He's one of the original 8 as they say, but I feel that perhaps, he's been axed. I don't think Yoshi was ever a great character so that could be a plus to me, but still, I just found it weird.
- I wanna know if they added an extra function to the gameplay. Perhaps another attack button, or a toggle of some kind, just to spice the game up.
- Final Smashes are back, so I guess Zero Suit Samus will also be in the roster. Of course, they could've made it so Zero Laser doesn't actually change Samus at all.
