I thought they said they were doing a new headsculpt for Wedge and that was partially why he's been so long delayed in the first place... IIRC.
During the film's release, Star Trek did sell well here... It stagnated here like everywhere else eventually though and a LOT was in the pipeline it seems because even where they sold out, more fresh cases wound up surfacing. You could always tell that if you saw Spocks and Uhura's miraculously turn up. So ultimately my area was the same there eventually. But during the Summer and into the months leading into Christmas stuff was moving through for that line. You could always tell because new stuff would turn up after pegs sat empty. Now, there's still a few of both playsets lingering on at Big Lots here. Such is life I guess. I like to hope a 2nd film will have new figures but maybe toned down dramatically.
The Rebel pilots are in abundance because they've got the molds, and no real reason beyond that I think. I'd like to get what we can, especilaly from the films, while Hasbro's willing to crank them out... I'm hopeful Rebel ground troops come out in abundance too, but so far Hasbro's not reissuing them like I'd like to see. Since I've kind of championed Rebel Troopers since going back when it was considered almost blasphemy to a lot of people to even request it, I think it's pretty established I've been anxious for new grunts on the ground. I'd like to hope that once they're all done, Hasbro maybe re-issues some of them. Maybe new heads too. I'd like to see some of them make the Legends assortment. I'd buy more if they were made available routinely. I'm pretty ok on anything in white armor right now unless they update the Scout Trooper with hips and a removable helmet or something. Unfortunately they're not going that route right now, for one reason or another.
