Yoda??? If they can to Jagga and his minions they can do Yoda
I hear what you're saying about diversity, but Jabba and his critters are not good examples for the ability to provide Yoda, they look great but have no articulation but for Jabba's arms, people are going to want a Sideshow articulated Yoda which will require a 1 of a kind body. I'll guarantee Vader and the likes are being worked on also, but they're being worked on and aren't yet up to the standards Sideshow wants them to be at, so in the mean time, we're being offered some great pieces along the way.
