Dhalsim looks great in this game. He just animates so nicely. I hope he is viable. It does concern me a little that the people that mained him in SFIV are struggling with him. That being said, I don't think it is time to hit the panic button yet. Firstly, the game is still pretty far away... Secondly, as people have already said, it only takes one person figuring out one thing to turn "garbage" characters into viable characters.
