After seeing all the work and interesting gameplay they added to Steve, I am excited.  This character and MinMin show there is a lot that can be done in this game to make the game really cool, and a new character fresh.  I hope the character is balanced well, because it seems there are many tricks and elements he can do that can break the game balance.  
I am sad Bomberman is just an assist trophy and now a Mii Costume, as I still believe he could have had a very unique gameplay gimmick.  Oh well.
