Actually, I don't think we need too many cameos this time. Yeah, they helped boost the last movie's attention, but I really don't think a large amount of cameos in the next one is needed. One of the things that people complained about the 1979 Muppet movie is the fact that there seemed to be too many cameos that didn't help move the plot further. If you look at GMC and MTM, the cameos do, in some part, move the plot along.
