I don't think the hair issues with Chewbacca would stop a Wampa. Overall, the Wampa has little screen time and minimal movement, so you could do a vinyl Wampa like Jabba, with basic articulation at the hips for the legs and shoulder articulation and it could be quite successful, I think with beasts and larger scale figures in this line, Sideshow's focus will be on visual quality more than poseability / ""play value"". With Chewbacca, they know people will want to pose and repose him over and over, with a Wampa, they know people'd want him going after looking in a few different, simple poses, and that'd be the extent of it, so long as the paint and sculpt were fantastic and stood out in a display.
