One thing that recently hit waves within fandom was a series of tweets that Leland Chee sent talking about how canon would be handled as things move forward. He basically said that what is determined as canon will now be decided by a group known as the Lucasfilm Story Group of which Leland and Pablo Hidalgo are members of. Now that George is retired it will seek to eliminate the hierarchy that currently exists and give everything the same level of canonicity.
Of course, many interpretations could be given to this, and many people have already given ridiculous reactions to this set of news. But their are a couple of things we can know from the new Lucasfilm Story Group:
1. Their creating some sort of master story plan: At the end of the day, what this all bogs down to is that most of the future content that comes out of Star Wars will be created by them. This will obviously eliminate the possibility of EU writers going into whatever direction they want, and giving us sometimes disastrous decisions in return. It will create a more cohesive version of the universe and one that doesn't fall apart the way the previous one did with its contradictions and over saturation.
2. Various Unknowns will now determine the future of Star Wars canon: Let's face it, the problem with this is that many are uncomfortable with the idea of someone new dealing with Star Wars canon, but it's somewhat safe to assume that guys like Dave Filoni and Simon Kinberg could be a part of the Story Group. In that case, we can be sure that much of the integrity of Star Wars will be repsected far into the future.
It's too early to tell how exactly this is going to impact everything but it's still safe to assume that a big chunk of the EU is going by the wayside (and some still are in denial about it).
