I found some of these at a local Target yesterday. I picked up the Sword Spike Thor since he appeared to be the most basic Thor currently available. They also had a one or two other variants on Thor, Odin, and one each of Loki and the Frost Giant, who I bet I'll regret not buying now. So it looks like just wave 1 is all that's available right now, and this Target got only one case, so hopefully Hasbro and the retailers aren't going to go nuts with this line like they did IM2.
