I think they actually shot a ten minute piece. I would be nice if they stuck that on the new Disney XD Muppets.com site thingy. Maybe some of that is the new content to come over the next few weeks. That would be perfect to chop up into little webisodes to generate interest in seeing the gang in something longer!
Before we got this site i would have thought no chance of them doing something like that, but they went as far as putting those new year clips up so it might be possible. It doesn't seem like its gonna be just the usual character intro video type stuff.
That site is probably the most exciting thing in ages to happen
