Oh no... that was decided a while ago. The movie was originally to be released in 2009, and we were supposed to have a preview of the movie on the third box set.... but that was if the movie didn't hit so many writing blocks. The treatment was written about 2007 or so, and the Henson company got wind of it a little later. They didn't have any financial backers, either. Plus, we needed someone to come in and write the screenplay based off the treatment. The script is only a little closer to the final draft, and even then we have that long period of pre-preproduction before the film gets filmed. I'd say 2011 is a good estimate of when the movie should come out.
After all, this isn't one of those annual "Parody" movies that they keep slapping together after seeing movie trailers, so they can get them out while the jokes are "current." God, I hate those....
