QUESTION: Could you re-make the Jawa Sandcrawler like you did for the AT-AT and Falcon. It is in need of an overhaul. I hope I speak for all the Droid/Jawa fans out there. With all the Droids from the Droid Factory line, it would be awesome to have a new Sandcrawler to display them in!
ANSWER: We would love to remake the Jawa Sandcrawler, and at one time started to look at what a super-sized version would cost in terms of tooling. The bottom line is that it would cost too much given the more niche nature of this vehicle.
Our most recent release (nearly 10 years ago) was lightly received by fans - one of the rarest vehicle releases of the modern Star Wars line, despite the fact it's a very tough vintage vehicle to obtain. It seems that this vehicle has some passionate fans, but overall it's too niche to be able to re-imagine any time soon.
It remains a dream for some day, but we can't let our passion for it override business sense.
QUESTION: Are you planning a new Luke in Jedi Outfit (Return of the Jedi) on Vintage Card?
ANSWER: Yes, we are. We are doing two things here: The current Luke figure on the EpVI card will actually get a running change to the card, where we will change the card art and the name to be "Luke Skywalker: Endor Capture." We will also look to introduce down the road another EpVI version, but details on that won't be available until next Spring.

Sad about the Sandcrawler but good to hear about Luke(s).
