Call me crazy, but I actually like Don Figueroa's interpretation of Jetfire for the Transformers: Generation One (ongoing series). When I first heard that Jetfire was returning to the comics, I thought it would just be a variation of Skyfire due to the design copyright issue with Macross. When I saw the preview cover for issue #3, I thought that I was correct.
However in the last page of issue # 2, you see an image of a Jetfire that resembles a valkyrie battleoid. While I do not have an image of that, here is the first two pages of issue # 3 to give you a better idea.
If you pick-up the book, the explanation for his appearance seems to go something along the lines of Dreamwave's Ultra Magnus. In his generic look, Jetfire looks like he does in the cartoon and Marvel comic book (ala Skyfire). When he puts on certain armor (ie FAST packs), he looks more like a valkyrie fighter.
