The pics have finally come out. And all I can say is, ‘Ugh’. A Santa-fied Yoda with the same old bug-eyed, spiky-haired head, Chewbacca has the wrong color bowcaster, and TLG skimped on pieces so much on the MINIs to the point that some are unarmed! Honestly, there are only 7 small pieces in that TIE/ln. You can do better, TLG.
Eurobricks has the rest of the non-confidential images all organized in one place on flickr.
