There are three Y-wings in the teaser art:

THREE.  There are also at least three A-Wings, assuming that the nose in the extreme bottom left is an A-Wing, but let’s just ignore those.

Besides, it’s hard to make fun of the A-Wing for its cinematic moment of glory being a human torpedo move into the bridge of a Star Destroyer when Y-Wings are chiefly famous for flying down a trench and getting blown up without making even a token attempt to defend themselves.

Did any B-Wings even HAVE a defining moment on-screen?  Apart from kinda looking cool when they locked S-foils into attack position?  Maybe I should rewatch the Death Star battle from Jedi again.  I don’t remember them doing anything particular in that.  Not that there are any B-Wings in this image as far as I can tell.

Anyway I have gotten off the topic, which is that this art has an acceptable number of Y-Wings and that the game is certain to follow this up by being excellent, or at least acceptable.
