Here's a video of upcoming LEGO Star Wars sets. I paid particularly close attention to the Star Wars Rebels sets. For two reasons. One I want them and two because it might reveal some stuff about the show. I was particularly interested in the Wookie gunship. They've been a part of an episode but not part of the rebellion or the show apart from being freed from Kessel. Also part of that set is a Jedi that doesn't have a "NEW" designation next to the minifig, but doesn't appear to match the Kanan Jarous that's part of the GHOST set.
When we finally get a Sabine mini-fig it'll be without the helmet. That's disappointing. However the Inquisitor and the TIE Advanced Prototype and AT-DP with Agent Callous both of those look like very very nice sets.
The question will be to start a collection of new in box sets or to build all of them.
