IDW passed along an image and clue about a new character to debut in a new G.I. Joe comic this month. If anything I hope we can find out if Chimera turned into Cobra Commander...and if the guy pictured really is Cobra Commander. Guessing game and info here: IDW G.I. Joe Guessing Game
Looks pretty cool to me..I would say it is an evolution of the movie design going towards the classic look.
