Specials
For kermit's 50th anniversary, maybe it would be good for Disney to release at least one special a month for a whole year. Of course, if Disney was releasing at least one special a month next year, I think we would have had an announcement by now.
Anyway, here is how i would do this:
January: The Muppets: A celebration of Thirty Years (or The Muppet Revue)
Febuary: Hey, Cinderella!
March: The Muppets Go To The Movies
April: Tale of The Bunny Picnic (or The Kermit and Miss Piggy Story)
May: The Muppets Celebrate Jim Henson (or Childrens Songs and Stories With The Muppets)
June: The Muppet Musicians of Bremen
July: John Denver and The Muppets: Rocky Mountain Holiday (or Rock Music With The Muppets)
August: The Muppets At Walt Disney World
September: The Fantastic Miss Piggy Show
October: The Muppets Go Hollywood
November: A Muppet Family Christmas (or The Frog Prince)
December: John Denver and The Muppets: A Christmas Together (or Mr. Willobys Christmas Tree)
I listed some alternatives just in case there are any legal problems. The Muppets: A Celebration of Thirty Years, The Muppets Celebrate Jim Henson, and A Muppet Family Christmas all include characters from Sesame Street and Fraggle Rock, plus A celebration of Thirty Years and The Muppets Celebrate Jim henson include clips from variosu productions not owned by Disney (and some not owned by Henson or sesame Workshop), whiel A Muppet family Christmas has always been edited due to music issues.
I listed some alternatives with both of the John Denver specials because I know that John Denver's family owns the rights to those special, or partial rights. But even if Disney doesn't own all of the rights, Rocky Mountain Holiday was released on DVD by Columbia Home Video when they had the rights to henson programs, so Disney could probably work out a deal to get the video rights.
I am sure that Kermit's Christmas Capers would probably be released on DVD next year, though it seems like it is now undetermined whether this special will be broadcast or made.
