If generations voyagers, Sky-Byte, Roadbuster and Brainstorm are coming. If they are new molds I would be delighted, but I think they may end up been retools of existing molds. For Sky-Byte they may use the Beast Hunters Sharkticon Megatron with a new head. Roadbuster could just be a retool of Springer and a new head. Brainstorm may just be Sandstorm with retooling with a new head, no headmaster but they could throw in a minicon instead.
Im saying this, look at Doubledealer who is a repaint of Blitzwing as an example. However new molds are just as likely seeing as we are rumoured almost certain to get a generations Leader Jetfire as indicated in another thread.
