What I can see in the trailer is that they show it off on the 3DS then it transition to the Wii U to show off the graphical difference. The game has your usual characters like Mario and Link, but it has new character called Villager from Animal Crossing and a special fighter, Capcoms Mega Man!
I have been waiting forever for this game and it should be a blast, lets hope we get at the end of this year in time for Christmas. Haven’t seen the trailer yet? Watch it above.
