Let's hope this factory change means better quality control, yep. I didn't encounter quality issues so far with my NECA figures either, but the many bad feedbacks I read were concerning. Perhaps they heard them.
Moreover, they can't mess with the coming Ripley figures and the Queen, Sigourney Weaver's likeness was tough to get and there are many long awaited figures in the next series, so they can hardly afford to disappoint their customers with the next figures. I guess this is the reason why.
