Yes, 20 points of articulation including the fingers, knees, hips. We have no idea how they count these points of articulation. Could be shoulder is one, elbow is two, wrist is three, head is four, waist is five, with one being a double joint(head). Or yes, it plus be they count shoulder(s) as two, head as a third, wrist as four and five and torso as six. But we don’t know. They didn’t list whichever areas are going to be articulated or how it’s counted. Again, we just don’t know. And given they don’t yet have a prototype that does any of it it’s hard to say what will or won’t be. You can believe one way or another, but there’s equal evidence either way.
If the figure has articulated arms, waist and head and wrists the only part that GoTG thanos has that’s more is his legs. His ankles I believe where considered articulated but don’t actually do anything to enhance any pose. Hulks arms are so poorly articulated they had to include a second torso to have him raise his arms. The difference between this figure, based on what hot toys said, and the thanos or hulk is much smaller then the difference between hulk/thanos and any other iron man or normal figure. Even at the stated 20 (remember that includes fingers) points there’s 14 between hb2 and thanos, and 20 plus between thanos and mk50 iron man.
So the point I’ve been attempting, and clearly failing, to make is that we don’t know what areas are articulated specifically, but based on their description it’s hulk or thanos without leg articulation.
