Currently no one knows who all of the playable characters in the game will be, however Nintendo has told us a few characters that will be in the game.

However, it is unlikely that Tabuu will be playable, since he is an original boss character for the SSB series, and so far no original boss characters for the SSB series have become playable. But Nintendo could still surprise us and make Tabuu playable.
