Well, I'm not sure the wave, but there seems to be a big influx of MU figures. Everything i have seen has been out before I think, except the "phasing" Vision variant. I picked him up along with some others for fodder.
Of note was Ghost Rider (they did such a great job on him!), Black Widow (probably the best female they made) and Jean Grey (fugly headsculpt, now I regret grabbing her).
Oh yeah, finally got my motherfucking Thanos!
