Yeah, the Clone Wars thing came to my mind as well. If what we actually see on-screen trumps the unseen portion of a thirty-year-old puppet then this might not even be much of an issue (unless, of course, Lucasfilm decides there are two different kinds of Ortolans....the two-legged, two-armed variety and the one that has just two limbs, and as we know from some other species in sci-fi/fantasy that's at least somewhat possible).
Either way, I don't think a new Max Rebo Band is on Hasbro's to-do list anytime in the near future.
