Well, I bought the DVD. I haven't watched it yet (I'm at the library now), and the Muppet Wiki page doesn't have a full sketch listing, but the DVD is 67 minutes long (I think that's the longest of the WB releases, excluding Follow That Bird). Interestingly, the packagign lists "Ginger Bread Man" as a bonu clip (and refers to it as a classic... I think that clips from the early 1990s, so don't consider it "classic" enough). This is the first character spotlight DVD to contain any bonus clips.
The packaging mentions that it contains "Cookie Monster Disco Song". I wonder if tha's referring to "Me Lost Me Cookie at the Disco" (which was in the promo) or "Cookie Disco" (which was listed with that title on Old School Vol. 2). I think it would be weird for the same DVD to include two disco songs with Cookie Mosnter (especialy if it means no Monsterpeice Theater or team-ups with Ernie or Kermit, not that I know if those two will be on the DVD).
The packaging also confirms that the three "C is for Cookie" sketches are mixed tgether (referred to as "C is fro Cookie Mash-Up").
EDIT: I'm watching this now, and this DVD actually has new linking footage (and so far it's better than the linking footage in Cookie Monster's Best Bites).
