Cars stuff always sells solid. Toy Story does too. Those are sure things, and they've never not been in stores. When the first Cars movie came out, the little die cast cars were impossible to find until they reshipped them. Disney has yet to see Muppet stuff sell to that capacity, but then again, they only owned them since 2005, and there hasn't really been much Muppet merchandise (though the Hallmark Keepsakes always manage to sell out before Christmas). That's why things are so slow with Muppet merchandise. They were pretty slow with Phineas and Ferb stuff too, but that stuff seems to be selling well.
