You might remember Masahiro Sakurai, he was the director of the original N64 Super smash bros and he´s also known for his work on Kirby games. Sakurai left Nintendo a few years ago when he was up to build his own company but know he has announced that he will come back to direct the SSBM sequel for the revolution. I´m sure he will do a great job, he has a great rsponsability in his hands since the game will probably be the most expected Revolution game.
