Although Target hasn't put their Dark Knight stuff out yet (that I've seen), it seems like the Movie Masters stuff (the 6" scale line) has sold through pretty quickly around here. I grabbed a few of them when I was out looking for Indy stuff on the release day, and I've just seen the same Clown Thug/Goon figure on the pegs since then. Anyways, these seem to be selling pretty well (or just not restocked at all). Meanwhile, I think the 5"/cartoony stuff is sitting pretty well.
TRU is the only place around here that has gotten DCUC Wave 2, Target seems to have had it at one point (Electric Supes left), but otherwise has just had Wave 1 stuff. I'm really looking forward to Wave 3 being released - that wave looks fantastic.
