I pre-ordered mine through GameStop, because I like being able to make payments up until release. The lockdown has prevented the payments part of that, and I'm hoping they'll open back up on the 4th so I can get it.
I love how eclectic my Mando bucket collection is. I have an old Hasbro Boba Fett helmet that I modded to be more accurately shaped. That's my custom Mando persona v0.5.... I have two Rubies helmets that are also getting refined. Both are for my Fenn Shysa costuming -- one ESB Boba colored for Clone Wars era, one polished nickel for after ROTJ when he was de-facto Mandalore. At least in the old EU. I want this one for my white Supertrooper build. And ultimately I'll be making my v1.0 custom out of stainless steel like the rest of my armor.
I also really hope Hasbro do Din's helmet as an upcoming release. I wouldn't mind Jango, too, but, as with Din, it'd have to be a fresh sculpt. Despite the similarities, Jango's helmet has differently shaped "cheekbones", differently placed right-upper earcap, and is about 5% smaller than Boba's. I'm annoyed the Black Series Stormtroopers didn't stick around longer. I only managed to snag three before the aftermarket price got up over US$100 -- two of them my preferred Amazon-exclusive Shadow Trooper versions (the black plastic is much easier to see what I'm doing when I work on it). I think I'd still like one more, at least. So many projects. Another I hope might come alone is a Phase II Clone Trooper helmet. Just like the Stormtrooper, they could crazy-go-nuts with store-exclusive re-decos based on all the ROTS unit markings. Makes me really wonder why they haven't done any variants of the Luke pilot helmet. There are at least fourteen alternate markings that I know of without even digging into the EU. I ultimately need five, though, whatever deco -- though if they released a Red Leader one, that'd save me a lot of time and effort.
