I'm not sure, Disney doesn't seem that much in a hurry to market anything animated, I think it will be a few years yet, and most likely they will be putting out all the classic muppet films again to go with the new movie. Maybe after that?
I've said it before. Disney just sucks at releasing box sets. They don't even have any for Phineas and Ferb, and that would be a GOLD MINE! All I ever see are crummy 90 minute movie sized compilations of the show.
I mean, I'm sort of grateful they bothered releasing unfinished sets of Darkwing, Ducktales, Rescue Rangers, Talespin and Gummi Bears, even though they were bare bones... but think about this:
When they rereleased Lion King to DVD, they didn't bother with the Timon and Pumbaa cartoon, nor did they bother releasing Buzz Lightyear of Star Command when Toy Story 3 came out. In theaters OR DVD.
Still, Diz managed to sub-license their TERRIBLE 00's era family sitcoms to Lionsgate. Why there's a call for According to Jim is beyond me. And why they don't do that with Disney shows (though they'd be claiming them up all over youtube... beats WMG doing it without actually releasing anything) is beyond me.
