Most people in this thread seem to understand, but I'd really like to elaborate on this topic for people who are unaware of the details of Star Wars' canon and Disney's changes in policy.
For a long time, Star Wars continuity has been divided into a series of tiers. In order, it's G-canon, T-canon, C-canon, and S-canon (there are two more tiers, but they're not canon). G-canon is George Lucas canon, and includes the six films. T-canon is Television canon, and includes the Clone Wars movie, show, and the planned live action show. C-canon is pretty much everything else, including games and comics (though if a game has multiple choices only one will be "truly" canon obviously). S-canon is Secondary canon, and includes older stuff that was written when there was less consistency. The term "Expanded Universe" refers to everything that is not G-canon.
What the order of the tiers means is that when two sources contradict each other, the higher one wins and is the most "official" version. In other words, if a video game says Luke Skywalker likes wearing red, but a television show says he likes wearing blue, then he "officially" likes wearing blue.
However, what's relevant to this thread, is that Dinsey has now formed the Lucasfilm Story Group to rethink this system. There will no longer be a hierarchy of canon. Things will either be fully canon or fully not. As far as I'm aware, there hasn't been any specifics yet. I'm sure we'll have things even down at S-canon made official, and things from T-canon abolished, but we're completely oblivious to any specifics. There will be no more "Expanded Universe," but that's only because the things that remain will now be on equal footing with the movies.
That's why the Hasbro thing is relevant. Not because Fantasy Flight Games has anything to do with Hasbro, but because it's more than likely that Lucasfilm's ruling on Hasbro will be applied to other companies that make Star Wars merchandise, as part of their initiative to simplify the canon. Obviously, Lucasfilm will want to focus merchandise on the upcoming films, but we know they're redefining canon, so there's no way that restrictions specifically on Expanded Universe merchandise is irrelevant to that decision.
What does that mean for the X-Wing Miniatures game? No one can say yet, but it will almost certainly mean something (even if we never find out). We know that in the past FFG was working closely with Lucasfilm, so it's possible that all of the Expanded Universe stuff in the Miniatures game so far has been approved, but it's equally possible from what we know that they just haven't started really cracking down yet. The only thing we can say for sure is that based on the Hasbro ruling, we'll at least get everything that FFG has announced so far.
