Umm... Pooh, Jamie and the others are talking about the projects done by The Jim Henson Company, not Disney and Sesame Workshop. I think you're confused.
But I feel the Henson Company is trying to find their footing again. Without the Muppets there to keep them steady they've lost some of their balance. They're trying to regain that again with more Fraggle Rock exposure, more Puppet Up! and these Fairy-Tale specials on DVD. I'm really not sure how well any of that is working... I think as of now Fraggle Rock is their best bet. I did recently see a clip of Sid the Science Kid, however, and that looked impressive too. I think they found the right thing there too.
