SDCC Exclusive Alternator Nemesis Prime?

TFW2005 is reporting a RUMOR, and I emphasize that this is just a rumor at the moment, that Alternators Nemesis Prime will be a San Diego Comic Con Exclusive. Nemesis Prime is a black repaint of the currently available Alternators Optimus Prime. This might not be that far of a stretch since last year Legends of Cybertron Skywarp was a Hasbro exclusive at the convention.

Remember, this is strictly speculative at the moment and has not been confirmed.
