If the new transformers prime toy line will be called robots in disguise does that mean that soon prime will be called transformers prime robot in disguise
No. There was already a Robots in Disguise show. There won't be another. The show will keep the title it has.
It will be so confusing when they make a new Optimus in that line, and when you say "RID Prime" everyone thinks you mean Fire Convoy.
My own speculation is that the RID toyline is going to be a catch all line so they can release prime toys in it and likely other things such as FOC toys as well as more classics. So we will have movie trilogy and robots in disguise line selling next to eachother. We will see what happens.
