Unboxed him last night, great figure and major improvement to the already excellent (though aging) first release WM. Articulation is indeed very impressive for a figure this bulky. The head doesn't seem to snap on the neck peg on mine, hard to tell if it's on properly, not sure if other owners experience the same thing. Under low indoor lighting the darker gray looks almost black and creates a sharp contrast with the lighter gray parts. I can't really say this is worth 2x the price of the original release but I'm also not hating myself for paying that much either.
Someone here asked how tall he is compared to the Mk3 DC, he's basically a head taller, not sure I'm going to display them side by side because of this. I may be able to hide that height difference via poses though.
