I'm definitely buying this! Maybe a double depending upon the price! I read through numerous comments from yesterday alone and see some liking him and others not. I never been a big fan of exposed joints on high end toys, so the lack of elbow articulation doesn't bother me. The other joints are acceptable enough to still make him pose-able and not looking too much like another Hasbro figure. I think HT accomplished a happy in-between. Like some else said earlier, this is a hard figure to do!
The earlier pics of him on display are just the lighting making him less green.
As for the leaner look, I recall the film makers saying his muscle definition shows better when he's straining or flexing. Judging by the face, this is probably the angry in-action portrayal of the character! Again, well done by HT! And thank god, no awful abdomen articulation like I seen in the Hasbro lines.
I personally hope HT leaves this one alone. I'm glad the arms aren't rubber since I've heard and seen pics of the problems with past figures such as Leonidas!
