any of these do it for you?
I do want to try to eventually get a Thor and Loki in 3.75" scale with their helms - I really don't want the versions that are currently clogging the shelves.
For the IM2 and CA lines, I'm sticking to just non-gimmick figures from the movies.
So for IM2 I have the Mark I - Mark VI, a squad of Air Force Drones, a squad of Ground Assault Drones, the two Drones that came in the pack with Nick Fury at TRU, Nick Fury and Whiplash. I never got the Target set with the Whiplash repaint and the Sea Assault Drone. And I'd love to get the "Concept" Hammer Drone since that looks the most like the armor that Whiplash wore at the end of the movie - but if they ever made a 3.75" version of that I'd definitely want it.
For Thor - I loved the movie, but I really only want Thor, Odin and Loki with their helms (as opposed to the versions that first came out), the Warriors Three, Sif, Destroyer and a couple of Frost Giants. But the only figures that seem to be around in my neck of the woods are the Thor, Loki and Odin figures from the first wave. Excellent planning on Hasbro's part!

For Captain America - like I said - I'm good with just the Movie version of Cap, Red Skull and a pair of Hydra soldiers. If they come out with a single carded Hydra soldier or a movie version of Bucky, then I might consider those.
The biggest problem I have with these lines is that Hasbro ALWAYS goes all Batman with the main character. There are only so many Iron Man, Thor and Captain America versions that you need or would ever want.
I will NEVER understand the "Comic Series" sub-lines in these movie lines. Isn't that what your "Marvel Universe" line is for? Figures based on their appearances in the Comics? That's where a lot of these figures truly belong. How about trying to plan on some form of synergy between your toy lines? At the same time you're putting out movie versions of the characters of Thor, why not have a Marvel Universe wave that includes a few non-movie Thor characters from the comics?
I want to walk into their offices in Rhode Island, dump truck load of IM2 Iron Man figures on whatever moron's desk has been planning these lines and beat the snot out of him, all the while asking him why they didn't learn ANY lessons from the failure of the IM2 line.
Just once, I'd like them to put out a good solid mix of characters from the movie in the first wave, thus at least getting some variation out onto the pegs. There is no reason why Destroyer and Sif - both of whom were in many of the trailers - couldn't have at least both been in the first wave of Thor figures. If you're going to have the Frost Giant deluxe having the exact same figure for a few bucks cheaper makes no sense, so the single carded Front Giant should have at least been dropped in favor of Destroyer...
Sorry for getting off-topic re: the Captain America line...
