I'm pretty sure Shiek will play the same role in Brawl as Melee. And think about how many characters we already know about. We also are expecting previous big characters from Melee. Marth, Cpt. Falcon, ext. Now why would they lock characters that have already been announced. They could lock ones such as Marth and others that we know. But think about how many unlockables that there were in Melee. There's got to be many more we'll discover when we buy the game.
