They've already spunoff with Angry Birds Seasons. Given the success of that app, I think they can build more Angry Birds Topical apps like:

Angry Birds Transformers. Angry Birds Harry Potter. Angry Birds Cars. Angry Birds Kungfu Panda. Angry Birds Democrats!

That's Angry Birds Seasons. New level sets for each holiday all in the same app.
