Captain Falcon hasn't been mentioned, neither has Ness nor Lucas, and of course, any newcomers.

When Brawl was in development, they used a site called DOJO!! to convey information to people. Game & Watch was revealed last, with no actual mention of him up until then.

Just because there's no Wario yet doesn't mean he isn't in the game.
