A little late to the party, but it's really nice having Muppet action figures in circulation again, and to echo at least a couple others in this thread, I *REALLY* hope the "unknown character" next up in the line is Cookie Monster.
I guess Elmo would be fine, but the idea doesn't intrigue me as much as a Cookie Monster figure, who by comparison is a bit more challenging to picture articulated and thus a lot more intriguing. I wonder if they'd give him multiple heads along with one head with an articulated jaw like they did with the Creature From The Black Lagoon, if they'll give him plastic neck layers to allow for more head/neck articulation, etc.
