If the rumors are anything to go by, if it did happen, it wouldn't be for at least another year. I think in the Henson companies current position (ie:- not much money) they couldn't really justify investing right now in something that isn't all that profitable or boosts prospects dramatically even though they'd like to. They know people want that kinda stuff - and are making more smaller appearances like Barnes & Noble, MOT&R, and the statue unveiling which the public can attend.
