I dont think the face on the new sculpt is new. I think now both heads will have the angry face but the newer version will just have the new hair. So the newer head should look pretty similar to the PO head.
Could be true. I think other people were thinking this, too. Not sure if we got any confirmation yet.
People get so confused over these heads though. Despite all the hair changes, there's only ever been 2 heads printed for this: angry head and the later calm head. The angry head's just been through various paint changes aside from hair to degree that it looks different at different stages of tweaking.
...the power of paint. The original PO head and hair is great, but it will mean nothing if they don't paint it like they originally did (no beady eyes like later versions and they need to add back the eyelashes around the eyes).
