I wouldn't call PTE a knockoff, since they don't try to imitate GIJoe in any way.
The cartoon was pretty decent, although it was comical how the soldiers all had their toy articulation drawn on their character models. And there was that silly moment where the kid was all starry-eyed and fascinated while bullets flew inches away from his head. Otherwise, good animation and action segments... I really liked the tank bashing through a building onto the streets, and the LAV taking some rockets to protect the Humvee. That's the sort of action I'd like to see in a Joe cartoon (something the allegedly-popular Resolute failed to bring).
I'd love to see those robots as toys, and those heads with the removable helmets are pretty cool, although since they're all Chinese soldiers, I think if the toys get imported we'll just get the older "American and British" soldier heads from the Marines, Rangers, Delta and SAS sub-lines of PTE.
