Our local WM has four pegs packed full of that Sentinel wave right now, and nothing else. Well, aside from the Face Off packs, there are quite a few of those as well. Which in a way is surprising, because they are very nice figures and a pretty good value.
I found the Spidey Origins stuff others have been seeing at Target today. I was actually pretty happy to find these because I never got a Green Goblin from the movie line, and kind of hope to have a "complete" movie set (without Spidey variants) someday. Now I just need to track down ones like J.J. Jameson and Mary Jane. They also had the "Signature Series" figures, and I picked up the normal looking Spidey. I think this is the only one I'll get from the line, but it reminds me a lot of one of my favorite (and first remembered) toys as a kid that I had, my MEGO Spider-Man. The others didn't look too good to me though, the Symbiote Spidey looks like he's wearing pants (cuffs at the bottom). No sign of the Shuttle at our Target yet, so I decided to pick one up. They also had the Electro/Toxin wave, so that must be hitting Targets now too (I had only seen it at TRU previously). Also, our Target has/had gotten the Mojo wave, and it seems like Longshot it sitting. There's a couple there and at TRU, and nothing else from that wave.
