(Perceptor) UPDATE from ToyFair! ...
Had a chance to talk with the game developers at ToyFair today about this game. Quite a revelation actually. Saw gameplay, high resolution image stills, chatted with the Activision team. The whole thing came as a very pleasant surprise to see similar continued use of some of the previous highly regarded video game designs. Rise of the Dark Spark has a story that incorporates War For/Fall of Cybertron and Movieverse... (Have fun with this one Sabrblade!

As you can see, a portion of it takes place on Cybertron, a portion on Earth (with Age of Extinction characters.) We were told that they brought back the same star studded voice acting cast would be returning including Peter Cullen as Optimus Prime and Gregg Burger returns as AoE Grimlock (at least in the video game) a great sign!
He told us that the gameplay will be similar to that of Fall of Cybertron. Multi-player cooperative will be available, but not cooperative campaign. Things looked great. Stay tuned, more to come!
