They will use the BW/BM/Universe cast like primal?
No, its set up as a completely different universe. One that is paralell to other known Universes. I guess it makes it easier for them to create the story and fit whichever characters they like in whereever. Currently they have (classic)Cliffjumper in the shattered glass world and the OFTCC combiner bits in the Transtech universe.

I must admit that I liked some of the Transtech designs that were floating around . Nice to see it being used IMO.
