I'm confused by your post. EA and BW worked together to make this game, so........ there is that.
As far as Disney goes, they did buyout Lucas so I'm guessing they could have input into the future direction of this game, the EU or anything else Star Wars related. The old EU has pretty much been classified as "Legends". All the new stuff is now considered canon. They did pay a big chunk of change, so they can pretty much do whatever they want.
