Funny, I saw them at Star Wars Celebration and thought Rizzo was a lot smaller than I thought he would be too.
I don't know what the outcome is going to be with these but I doubt either muppets they have in the works would be very successful after seeing them in person. Darn, it seemed so promising in the beginning.
Sorry to be pessimistic, but I really don't see any way eFX is ever going to get these things out there. Way too much time has gone by to re-build the kind of momentum they've lost and the economy is just way too crappy.
