I was reading on TFwiki and another wiki site about GPS. And I noticed the part they talk about the plastic swirl. And as seeing that a toy as new as 4 years ago (Superion) has suffered from this, I wonder if they will ever solve the problem. But anyways, if you look at ROTF leader Prime, the exhaust stacks have a silver rubbery plastic with a swirl to it's makeup, or at least mine does. And also Universe 2.0 Cyclonus was previously mentioned by someone as having silver plastic with a swirl to it. Could these be future possible toys to look out for having GPS? I have just noticed that alot of ROTF toys have silver plastic and it makes me wonder. Anybody out here really familiar with the true causes of GPS have any take on this?
