In line with the coming Transformers game, War of Cybertron, Hasbro will be releasing Transformers toy design in that game.
For Autobots, there are Bumblebee retaining his classic head design but a twist to the vehicle mode which is rather sleek and futuristic in Cybertron.
Optimus Prime on the other hand still look like him in robot mode but the vehicle design was something new breaking the usual truck design style.
For Decepticon, here's Megatron. Much of the G1 design remain in robot mode but the vehicle mode, Megatron taken the shape of a tank.
So far so good. I will be eyeing on Bumblebee and Optimus Prime when they are released.
