I know what you mean. To me, I wouldn't get this Luke as a stand alone Luke figure. I would only acquire him if I was going to get the ROV Rey (which I am) to recreate the last scene in TFA (which I plan to do).
Also I still don't know if the robotic hand on the figure is a fixed posed. From what the expo pics show, the hand is still in the exact pose as it was at SDCC. Most definitely will not buy if you can't move the robotic fingers
