Marvelous Kingdom
Let me just toss in a disclaimer here before you think I've gone rabid raging fanboy here--I actually think Disney purchasing Marvel Comics is a good thing. Marvel, despite the gobs of money they've made on their movies as of late still never seem to get their ducks in a row financially. Disney on the other hand actually respects a franchise/brand/company when they buy it, believing in the old adage of not trying to fix things that work. ESPN, ABC, Jim Henson Productions, etc.
However, the marketing aspect will ramp up even more. But then again, Spider-Man bubble bath has been around for years, so maybe it won't be as noticeable.
Besides, I could go for a Dr. Strange/Wizards of Waverly Place clash, or the Banshee taking down the Jonas Brothers. Hannah Montana in spandex I'm sure would get a lot more boys to watch her secret identity.
