We have some confirmation that Warpath is going to be in War for Cybertron as a tank in the Autobot campaign.
Also, TFW2005 posted that Skywarp and Thundercracker are in the game as Decepticons, but not necessarily playable. I would bet my right arm that they will be playable alongside Starscream in the jet levels of the Decepticon campaign. Who else could be chosen as jet-level characters? Obviously any of the cone-heads (Ramjet, Dirge, or Thrust) or possibly Blitzwing or Astrotrain. It would be cool if Blitzwing was playable and had the ability to be a jet during the jet levels and a tank during the land-based levels. At this point, anything is possible!
