Can you point us in which corner of the universe this may be from?
I'm actually trying to *not* do that due to the planned Comic-Con reveal by Hasbro. There's a hint in the image, but odds are it won't help you in your guessing. At least one of the figures in the shadows is indeed part of the set. The others, not so much. Trust me, if I were in a position to tell you what this is, I'd be telling you.
If you like the kind of things we've done so far, I'd say you will probably like this one. I'll also say that nothing in the set has been revealed/leaked yet to my knowledge, as the Twi'lek female Rebel pilot's place in the line is still a mystery to me. (Aaaand if I didn't already say it, I did have input on this one. Biased fanboy seal o' approval here.)
If you pre-order the set and don't like it after it is revealed, you can always cancel your order with no penalty, or return it. If someone wants to be in that very first shipment of every item ever made, well, here's the chance. First-come, first-served.
