Incorrect.
Plastic is on the left. 1st gen Premium is on the middle and second gen Premium on the right. There is additional mass added to the legs for the corrected release.
Is that your photo? I ask because the pictures of unassembled 2nd wave PH compared next to the 1st wave PH I saw back when they first shipped showed negligible change to the legs (maybe Catalyst was still shipping out the originals?) The rightmost mech looks more like an example I saw where someone shaved and glued together the legs from two different sets (my current plan if there is no resolution from Catalyst). I'm not sure what's original with the middle one since it's been modded so much.
In any case Catalyst hasn't specifically acknowledged the changes at all (saying "fixed" isn't enough when there are so many questions about the product) and I, like many others, are still waiting to hear back from support tickets submitted last year on the issue.
MFC does great work with their cyberpunk figures, so how the heck these things are having so many problems between the two companies is mind boggling. Isn't someone knowledgeable of the product line at Catalyst at least opening up a pack and looking at it?
