Most likely EU will become the STANDARD and the films will be put in the back when it comes to Canon , like how it is for DC and Marvel .
To be honest , it might not happen today or anyday soon but it won't be long before Marvel takes over the Comic side of EU .
I really Doubt Disney is going to outsource EU Comics to another Company when they own one of the Two Comic Power Houses ...........Marvel ! This does not mean Marvel will do it better or worse , that will be yet to be seen . I think Darkhorse did a good Job in my opinion !
So its not a coffin , but it might be a rewrite of the EU Lore and Story.
As I said before , Luke being married to Mara Jade is likely now the TOP Canon now ! To be honest this is the reason I am happy Lucas is out the way , now the series can grow and G-Canon will no longer stop it !
But thats not gonna happen is it. Marvel started off as a comic, so the comics take precedent. Star Wars started off as a movie, so the movies are going to take precedent. Most likely this will become G-Canon, he isn't entirely out of the picture and never will be. What it will do is open up new avenues for EU, which is a good thing - if anything it will breath new life into the period of EU which doesn't really have any foundations apart from the Original trilogy, it will also tidy it up a bit, which some people may not like.
