Budget Stark just put up Hot Toys' release schedule updated on May 5th, 2017. It's still showing the Hulkbuster to be released in Q2 of this year. You would think that if they wanted to push it back they would have done it by now.
I'll bet based on this we'll see in the states in August.
BudgetStark put out an "Upcoming Releases" video right before HulkBuster was delayed. Sadly, he's just as in the dark as the rest of us when it comes to this piece. Wouldn't get your hopes up until we see this guy released in HK.
