I know that Nestle makes Wonka products, I don't know if that means they have the rights to the Wonka name.

I can see a whole Wonka themed area, complete with the chocolate river as well as maybe a ride that you would experience if you were one of the rotten children, like you get to pick if you want to be shrunk, blown up like a blueberry, or go down the garbage chute...

As for the whole old vs. new movie, I like them both for different reasons. The old one has great music while Wilder portrays the crazy side of Wonka. The new one has dark humor, like most Burton films, and Depp's portrayal of Wonka seems to be more secretive and tragic.
