I just realised I hadn't given you my thoughts on this after seeing it at STGCC. The production piece had the smaller pouches on the belt and they have gone back to the sculpted dreads instead of fabric ones. Both of those changes improved the piece IMO. Overall, it looked great and looked exactly like the prototype. That also means that the smoke looks exactly like the proto, so anyone who didn't like it back then won't like it now either. The day prior to the convention I had gone to Simply Toys, and they had both the Mythos Boba Fett (which I had never seen before) and the PF which is on the Cloud City base (which I currently own but it boxed up in storage) next to each other. Both of them looked very nice, but I was blown away by the detail and paint on the Mythos piece. The only thing I didn't like about it was the size.
So comparing both of those to the XM, the Mythos is the most detailed and the XM is the most dynamic. After seeing the PF next to the Mythos in Simpy Toys it reminded me how much I prefer fully sculpted to mixed media. Then seeing the Boba, Maul, and Luke next to each other at the con drove that home even more. They looked SO amazing together. Boba and Maul looked particularly great next to each other because they both have the action poses. So right now I'm planning to sell my ESB Cloud City Fett PF once I get the XM one in. I love that it's fully sculpted, I love the action pose, and he looked fantastic next to Luke who I'm definitely picking up. Drawbacks would be the smoke for those who don't like it, and it doesn't have the level of detail or realism that the Mythos has. I do have a short video of Boba which I haven't uploaded yet, but I wish I'd taken a longer one. I was focusing on getting videos of the newer pieces and then by Sunday I was pretty exhausted.
I've heard it might be shipping in the next couple of weeks, which is exciting!
