Hot Toys dropped the final production images for their Power Pose (PPS005) Hulkbuster from Avengers: Infinity War earlier today and now is available at their Secret Base location in Hong Kong.
This is not a surprise given that this figure was prominently featured in the Hot Toys quarterly release photo at the beginning of the year. This is still much earlier than the originally projected time frame of Q2/Q3.
The early feedback appears to be positive. YouTube reviewer budgetstark noted that there is one battery compartment that handles all 18 LED lights.
This should release from Sideshow as early as next month.
