Throwing my hat into the ring here; I'm upset that I, II, III, V, and VI are missing the Fox logo and fanfare as much as you are.
Sure those films are solely Lucasfilm and they made them and Fox simply distributed them, but to me, they're still Fox films.
I suggest we contact Disney tomorrow and ask them nicely to right this wrong.
Ah, this makes sense. Lends credence to the idea that Fox retained some rights related to 1977 Star Wars.
