Yes but, like you, and I, said, X-Wing Miniatures is based on the EU. Where it has 4.TIE Interceptors, while they have 4 lasers in the Legends EU, which X-Wing Miniatures Game follows, only actually appear in one source in the current canon - ROTJ.
And in ROTJ, Interceptors have the same laser cannons as TIE Fighters and TIE Advanced x1s. Upon watching ROTJ again, it seems Interceptors do have the 4 wing tip lasers too, making 6 cannons canon
Theres a hierarchy of canon, and the movies are at the top. Most of the EU is wrong.
