Is 7.3 the final content patch of Legion?

Isn't it weird they didn't make a cinematic for the big final raid? They did that in the past, right? They always briefly showcase the bosses in those trailers. Siege of Orgrimmar was probably the best one. Antorus doesn't really feel that important yet.

Antorus doesn't get released until after 7.3.2 drops.
