Heh, some of those are arguable. Especially Ghostbusters.
I'd like to hear more about the rumoured games. The Beatles just cannot be what I'm thinking.
I think everyone's expecting Kid Icarus to return, and popular demand may take over Nintendo there (or some other money triggering scheme). I don't think there were any plans for it in the Brawl stages though. Found some sketches for when I was looking it up a while ago, and they looked excellent. Photoshop, eh. :/
