I'm hoping the "three unlockable figure tiers" are three more all new figures as well, so we get a total of six.
I don't see how repaints, repacks and resculpts would drive orders.
While I would love for all of the HasLab pack-ins to be Cantina Alien weirdos we don't already have, the way Jayson only called out three of the figures to be "all new" leads me to believe that we're getting a combo of all-new, never made before characters and some new resculpts (hopefully for things like Wuher or Hammerhead and not wasting slots on resculpts that would sell in the basic figure line like Old Ben or Farmboy Luke).
I hope I'm wrong and we're getting 6-8 first time cantina dudes, but I'm way too pessimistic to believe that could happen (even in a HasLab).
