There's one thing I've been thinking about, and I also saw this brought up on the toughpigs forum (after I thought about it), but although the Muppets seem to be bigger now because of the movie, most of the stuff that the Muppets have done since the movie has been promotion for the blu-ray release. The biggest Muppet appearances that weren't promotions for the movie or blu-ray release have been the Jim Henson's Musical World event and the Canadian "Just for Laughs" special, one of which won't be broadcast in America and another that won't get an official release at all.
While there seems to have been more Muppet merchandise in the last year than there'd been since Disney bought the characters, it still seems small, and a lot of it is stuff I haven't seen in person (not just the Disney Store/theme park exclusives). I've seen the books that came out when the movie did, but since then the only books I've seen in person are the Tales of a Sixth Grade Muppet sequels and many of the Marvel comic reprints. I have seen certain Muppet clothing items (especially Kermit and Animal hats), and some plush, beanies, and puppets at Toys R Us. The Muppet Christmas Carol was recently released on blu-ray, but aside from that there haven't been any new DVD or blu-ray releases of the Muppets past productions this year (hopefully the reliable source who said Disney wants to release the next season is more than correct, and hopefully we'll also get some non-movie/non-TMS DVD releases as well).
Hopefully the "All I Need is Love" music video will be great. I wasn't too impressed by the song, but that doesn't mean the music video will be unimpressive. I'm hoping it has lots and lots of characters.
