The new brand of TIE fighter looks like somebody just tore off one of the solar panels from the triple-winged cloaking TIEs in LucasArts’ Rebel Assault II.
It does kind of look like a Phantom, doesn’t it? Only differences are the aforementioned wing, and it uses a standard TIE cockpit rather than one that looks like it was ripped off the Falcon.
And the fact that we can actually see it.
