Firstly, it seems the leaders, Grimlock and Blackout, will look a lot like their on screen apparances but have very easy transformations. This was hinted at with the bigger panels present on leader Blackout in the leaked images with his feet resembling Leader Ironihide's. The transformation might be on par with that release in terms of complexity. The fan comments on the great deco and paint on Grimlock but says that the weapon (hammer) can not be removed due to transformation. Grimlock's T-Rex mode is said to be about 40 cm long but hollowed out at the bottom. Blackout will come with a small Scorponok (pictured below).
Voyager Optimus Prime has a similar Transformation and design to MPM-4 (and thus Revenge of the Fallen Optimus Prime) with good poseability. Starscream will come with his rotor blade (also pictured below) and the design of the toy is similar to the Dark of the Moon deluxe.
Keep in mind, these points are translated from Chinese so some parts may be lost or misinterpreted.
