When the old EU was officially discontinued last year, I heard some people saying "chill out, this isn't gonna be any different from what the Marvel or DC movies did."
That's a very flawed comparison when we consider the fact that the new movies share little in common with the last twenty-odd years of material. On the other hand, since all of the new media going forward will exist on the same level of canon, maybe they're just going to let the new movies do their own thing* and use the ancillary stuff to salvage certain elements of the old EU.
When I first read joefavs description of the big reveal at the end of Aftermath, it seriously sounded like the end-credits stinger of a Marvel movie that only the "true fans" would pick up on.
*speaking of which, do we know if the new Lucasfilm story group are having any input on the creation of these new movies, or are they simply there to connect all of the other media back to what the movies decide to do?
