A "Story Group" has been created by Disney to steer all Star Wars lore from here on out - and their initial mandate is to streamline the existing, sprawling canon. Which basically means that the expanded universe is under review.
It stands to reason, with the in-universe chronology of the latest trilogy, that everything post-RotJ is going to get seriously shaken up.
Logically, I understand the reason to do this - for Star Wars to continue; to not stagnate, and to stay alive in order capture the imaginations of new generations, it has to be rebooted with tighter continuity control (and it can be conceded, that much of the EU could technically be considered of substandard quality..).
However, despite the sense this makes, I can't help but feel like my childhood is at a firing squad. ._.
