Yeah, sorta. As I understand it, it depends on who you have an association with. From Hasbro/Takara's point of view: Hot Toys are a second party. Us consumers are also a second party. Unlicensed manufacturers are a third party as there is no direct association.
To us consumers, we are the first party and Hasbro/Takara and unlicensed manufacturers are both second parties.
I think that's right. :o
