I picked up Loki a few days ago at Target, not a bad figure.
Really I envisioned custom fodder for Star Wars when I saw him, and some of the other figures look like decent fodder as well... the Thor ones have really cool chest armor which I could see being used for Star Wars customs, but the figures of course are constructed in a way that makes it harder to work with.
Also the 3-3/4" stuff looks pretty good from what I saw, and that included Odin and the Frost Giant. The one real issue is too many versions of Thor - they should load up with more bad guys in the line, and God forbid, some "non aggressive" characters. Variety helps Star Wars so much, I don't get why Hasbro doesn't do that with more of their lines.
