I'm guessing it's one of those two that you just mentioned there Travis. Seems like the Sandcrawler is one of the last ships left to be made still, so perhaps that's the one.
Still, Lego's lack of Star Wars news lately, and any new set announcements, is making it really tough to be enthused about the line much these days. Just some new packaging and a couple rehashes lately, but that's about it.
I really wish they'd do something more with the mini-line of ships. That's my favorite. Love those little guys!
