Can I just add that Star Trek's EU is doing really well right now?
I read Alan Dean Foster's movie novelization, and I want to pick up the Into Darkness novelization soon.
And the comic series is so much fun! They had a movie prequel miniseries (Countdown), a companion miniseries that explained what Nero was going during his 25 years stranded in the new timeline (Nero), a prequel miniseries to Into Darkness (Countdown to Darkness), and the Ongoing series has many really cool alternate approaches to old TV episodes, plus some new stories too. They had re-tellings of Where No Man Has Gone Before, The Galileo Seven, Operation Annihilate, Return Of The Archons, a cool new version of Mirror Mirror (a mirror universe of the new timeline), and a handful of new stories, like Vulcan Vengeance and a backstory for Keenser.
They're up to issue 22, which came out last week. This arc, After Darkness, is a direct follow-up to the consequences of the newest film. And it's a lot of fun (though I don't care much for the art). Also, the TPB collecting 17-20 is out this week. Once I get that, I'll have the whole series (TPBs for 1-20, Countdown, Nero, Countdown to Darkness, and the odd prequel Spock: Reflections, and 21-22 as issues).
And all these stories are supervised by Robert Orci (who worked on the movies too, and with Alex Kurtzman is one of Abrams's go-to guys.) So they're all basically canon, if never referenced in the movies.
So yes, don't count out the Star Wars EU just because it's Abrams. It may change and evolve, but it will likely go on.
