We saw the G1 reissue of Blaster which we already knew was coming due to the Fan Vote. This will be a Walmart exclusive as with all G1 reissues. They also showed a Blaster shirt, exclusive to Hasbro Pulse.
There will be a weapons pack and Centurione Drone set, meaning that the image we saw earilier is indeed of a toy coming out. We also have an image of the weapons that drone comes with. It includes Roller, Megatron in Blaster mode along with a bunch of other neat things. This will be exclusive to Hasbro Pulse.
There is also:
Amazon exclusive Alternate Universe Optimus Prime
Selects Tigertrack
Selects Rotorstorm
Walmart exclusive Transformers R.E.D. line (G1, Prime, Beast Wars, etc.) - Optimus Prime, Megatron, Soundwave
Two other pieces of news were confirmed. Firstly, we will be getting an Autobot Clone two-pack and, secondly, the Transformers RED series will include characters from all different eras. So that Arcee listing will most probably be of the character from the Prime show.
