I got that, but still: That is just not correct. There are many possible reasons and they can't just do it.
You can copy everything that is protected by a copyright of course, but ONLY with a license by the copyright's. TFs probably has a license to build this 85' Lam.
In our case, Hot Toys can't just go and bulid a 1/6 Lambo. They would have to get a license by the copyright's owner. If they get it and if they like to make one, there will be one.
If they don't get a license and just built it anyway Lambo would probably take Hot Toys the court...
One possible reason why they might not ever bring it could be, that there might be other toy car companies with exclusive rights to copy the specific Lambo in this scale.
Once again: PM me if you have further questions but trust me, you can't just copy any design after 2 Years as you said.
