(At least, the next one after he sees my email)
From Game Informer, current issue, page 61.
"Specter wanted Oswald the Lucky Rabbit [1] to be the centerpiece of Epic Mickey. But that wasn't possible until a years-old dispute was resolved. 'Disney didn't own the rights to Oswald,' Spector explains. 'So there was no way I could use him as a character in this game.' But Bob Iger, the CEO of Disney, went to NBC/Universal, which after 80 years owned the rights to Oswald, and TRADED AL MICHAELS, a human sportscaster, for the rights to a cartoon rabbit."
(Technically this is old news, but since I hadn't heard about it, I'm assuming Simmons hasn't either).
[1] The first character created by Walt Disney (prior to Mickey).
