I like that they've been getting a lot of use out of the newly-rebuilt characters, including here and the OK Go video, but it seems they use the same characters that hadn't been used for years. I find it odd they haven't been using Thog or the Mutations for these (Sweetums appeared in both). I know I should be happy we're seeing so many characters in these that he haven't seen in years, and I know that the movie will have more. Too bad they didn't at least put Lips with the band. It would have also been cool if they'd put in some more Muppets Tonight characters (Johnny Fiama, Sal, Seymour, Clifford... They probably would have been silent and in the background, so they wouldn't even need the original performers).
One thing I really like is that it resembles the first season theme. That is cool.
I find it interesting that Walter hasn't appeared in this or the OK Go video. But somehow I feel it wouldn't be right to include him in anything before the movie comes out, excluding promotion for the film (so this sort of is, but it very well could have been a regular commercial or viral video).
