For now Hasbro Asia and Takara Tomy have not plans to address MP 44 knee ratchet issue
Although we don't have any posted on the website we did purchase a few of the new Takara Tomy MP 44 Optimus Prime from our vendor in Asia. The sample we opened has the knee ratchet issue as well and likely the rest of the figures we purchased do as well. We contacted our vendor and this is what they had to say:
""We have heard from hasbro Asia that TT didn’t treat it as an fatal issue and have no plan to recall it at the moment"
Disappointed to SAY THE LEAST!
