Would not be surprised if the factory that made the TFA buckets is one of the ones they did not pay (or whatever is going on behind the scenes) and they literally couldn’t give you one if they tried.
Everything I've heard points to Disney getting priority over preorders for fulfillment. It's entirely possible Anovos has been sending all their inventory straight to the parks while we get to continue to wait.
We don’t know for sure yet. Might be more new troopers in TRoS and/or more changes than we think to the FOTKs.
If, after the movie comes out, it’s deemed that they are the same or mostly the same then we’ll probably merge the forums.
Short answer: No.
Longer Answer: Don’t do it. For the amount of effort it would take to make it 501st approvable it’ll be easier to find an Anovos bucket, I see them go for $200 and under.
