I can see them cherry picking characters and concepts from the EU ala Thrawn much like how Marvel's Winter Solider movie took a chunk of Winter Solider's story from the comics, but it wasn't beholden to viewing the comics as canon to the films. Same deal here (not that I say I think Thrawn will be the villain of the ST but I think he'll be used in some medium going forward). The EU will be used in the Disney era to take things from much like how TCW did. TCW didn't try to keep the EU as canon but there is a hellova lot of EU in TCW. I think the notion of a character being the exact same thing across all mediums is kinda wonky. When something jumps medium, there is going to be an inherent change to it because they've literally jumped from one medium to another.
