The tweet Kilroy refers to was from Pablo Hidalgo back in December. It caused quite a stir because he basically said the only things that were ever "canon" are the movies and the clone wars series. In other words "only what's up on screen." Everything else in this model is merely "continuity."

Was able to track it down. That does muddy the waters but it wasn't an official statement of policy. It was an off the cuff remark.

If their intention was to completely do away with the EU then they wouldn't have been so quick to cobble that retcon together for the Korriban/Moraband debacle.

We'll have to wait for an official announcement before we know where the dust has settled.
