I think the deluxe release was a cool move by HT because, yeah, they probably could have sold a fair number of the promo versions as a separate figure. It's what I wish they'd do with Jedi Luke & the Endor gear. Instead of milking a second release with just a poncho and helmeted head sculpt added to the costume, it would have been nice to have a deluxe version with those parts included - similar to this Boba Fett deluxe version. Maybe that's actually the plan, and I'm just out of the loop.
And I have a question for the Fett experts, please. Did Boba switch the pockets under his ammo belt at any point during ESB? I used to think that the Sideshow pocket flaps were just lined up wrong due to an oversight on their part, but now the HT Boba has pocket flaps facing the same wrong way as the Sideshow figure. I say "wrong" way because I've never seen movie images that match. Here's an illustration of what I'm referring to, with arrows pointing to the pocket in question.

I'm sorry if this has been addressed before, but I haven't come across any of the discussions about it, and it's just bugging me.
