I don't know what "w/c" means but obscurity from the comics has nothing to do with what I said. Don't even know why you brought up GotG.And you're excited about Guardians of the Galaxy w/c is more obscure than these characters.
And you don't know anything about their roles to say that these new characters will not be important enough to warrant excitement.
At promo cards he was Bolivar Trask, or it was just fanmade?^He was called as Secretary Trask.
You may be right they're probably brief cameos unless the movie gets cut into two parts. Very few of them were at Comic Con.None because none of them will be important enough to warrant excitement. It would be like me getting happy about seeing Jack Taggert/Firepower in IM3.
