All characters unlocked in SSE?

[dtekdahl00]

I know the roster has been confirmed to be either 34 or 35 characters, and I'm completely pleased with the selection. But I still want to know why Sakurai is quoted as saying MOST characters are unlocked through Subspace Emissary, and ALL the characters that have been unlocked so far have come from SSE. Why is this? There are still classic mode, all-star mode, etc. to play through, did Sakurai just change his mind and have them all unlockable in single player?
