Fair point. And completely true. However, my understanding is that all the new media being released from now is apparently considered canon and being done with the intent of working cohesively with the rest of the canon.
I hope you are right. IMHO, I'd enjoy consistency from film to film (going forward), rather than writing themselves into a corner with too much EU stuff. [Don't get me wrong, I enjoy it when fans love the movies and they fill in the void left by TPTB, who made money off the EU licenses, too.] That has happened with Star Trek, and may well be why Star Wars jettisoned their EU. From a writing standpoint, it is much harder to sail the seas of good stories if there's a hidden reef of EU on which to ground yourself horribly.
Having said that, official books like The Alien Vault
and the Weyland Yutani Report
are great to see and sell well with this niche market. A nice compromise between establishing the official party line vis-a-vis The Official Backstory and making money off a great franchise (when handled consistently).
I remember the good old days when there was a novelization released before just about every science fiction movie hit the theaters. Confusing, if not entirely based on the script or finished film, but so awesome for context.
(I had a point to make here somewhere...)
