Still trying to dig up all the latest answers from Hasbro, but I think this is a good start even though it has already been rumored for Grimmy....Though I'm sure they'd make his tale shorter for safety reasons or some bull**** like that.
2) Will we see American versions of the Masterpiece Grimlock, Thundercracker, and Skywarp figures?
We feel that the Masterpiece Series is a great offering that captures the timelessness of our brand for all fans of Transformers. As we continue to move forward with the brand we will look for the right opportunities to release these figures. With that said, I would certainly keep your eyes on the look out for one of these in the near future!
