I'd buy a rehashed Bantha easily. It's the only POTF2 beast I lack.
I'd also buy a repainted Tauntaun and Dewback, regardless of what the quality of the pack-ins would be. I'm curious to see what the big H can do with all they've learned in the years since regarding paint.
And I can't fathom why they haven't made an ROTS style Eopie. Criminy, a pack-in Obi-Wan and Luke, or even Owen and Beru would go over well. I'd like to see it happen as a TRU exclusive, since I don't think it'd happen otherwise.
