I don't think the unmasked headsculpts are done as much for selling but the sense of being complete on top of keeping up with the standard they've created. I feel like because of the last scene with him flying Tony over to the wall and having the helmet off the Patriot will def. come with it where the gray promo/trailer version wouldn't. I think between the two I'd definitely display the Quantum without a helmet full time and keep it on the Patriot!
Out of the three War Machines definitely coming ( IV, VI, Patriot; I get giddy typing that,) which are you getting and which are you looking forward to most? I think this is my most anticipated just because I feel like a promo recolor of the Patriot is a given and will probably knock my socks off in comparison.
