At first many though that the Wii U version would share the same roster as the 3DS version of the game much like Smash. This trailer proves that theory wrong though since Boom Boom and Toad can be seen with team Mario and some of the characters are not there at all.
This video shows what classes the new characters are under.
So the classes are now this. Star means playable in both versions.
All- Around
*Mario
*Luigi
*Bowser Jr.
Birdo
*Wendy
*Larry
*Amy
*Blaze
*Espio
*Sticks
Speed
*Daisy
*Yoshi
*Diddy Kong
*Nabbit
*Sonic
*Shadow
*Metal Sonic
*Jet
*Wave
Power
*Bowser
*Wario
*Donkey Kong
*Rosalina
Roy
*Dry Bowser
*Knuckles
*Vector
Omega
*Zavok
*Zazz
Skill
*Peach
*Waluigi
Dry Bones
Ludwig
*Tails
*Dr. Eggman
*Sliver
*Rouge
Cream
Eggman Nega
Based on this list Power and Speed are unbalanced with 11 and 9 characters each.
Finally this video might give hint at some of the other characters who could be exclusive to the Wii U version.
So based on all this info here's how I think the Wii U version's roster will turn out.
All- Around
Mario
Luigi
Bowser Jr.
Toad
Wendy
Larry
Amy
Blaze
Espio
Sticks
Speed
Daisy
Yoshi
Diddy Kong
Nabbit
Lakitu
Sonic
Shadow
Metal Sonic

Power
Bowser
Wario
Donkey Kong
Rosalina
Dry Bowser
Knuckles
Vector
Omega
Zavok
Zazz
Skill
Peach
Waluigi
Dry Bones
Boom Boom
Tails
Dr. Eggman
Sliver
Rouge
Cream
Eggman Nega
With those small changes every class has 10 characters each. Eggman Nega, Dry Bones and Omega return since there models can just be reused, from being rivals in the past, the green flag shown on the boxart makes it seems like Lakitu or Koopa will be joining and Cream is to popular to take out. In my dream roster everyone stays and Charmy and Storm join the roster to balance things out.
