Thanks to "oni" here is a possible new screenshot from Transformers: Dark of the Moon that shows of a yet unseen character named Blitzwing. The character is a Generation One character and one of the first triple changers with alt modes of a jet and tank. The character was also in Transformers: Animated, with the same triple changer alt modes. Judging by the wing span and the treads on his arms, this movie version shows a strong possibility of continuing the triple changing tradition for the character. With a motto of "Destroy first, think later" hopefully this character will be part of lot of the action in the movie.
I don't mind the pic. Blitzwing would be awesome in DOTM especially if he is tri-polar like in Animated but there is a lot of speculation that this is fake
