Yeah, a lot of them seem like they're struggling to keep value. Even the flametrooper that was just released seems like it can already be had for $200. I bought the Snowtrooper on a whim cause I really liked the design but I'm sure they wouldn't have wanted to make a figure that had 2 seconds of screen time and some clunky deleted scenes.
Even the onslaught of different stormtroopers was a little silly, with figures like the Jakku trooper undercutting interest in the heavy gunner. I think they've produced or previewed (Finn) all but the black pauldron one in under 7 months from the movie's release. And released a gray pauldron one that might have been in he movie?
