Kotaku is reporting that Disney has admitted that all of Bioware's Star Wars games fall outside of the official canon for the intellectual property. Anything that is considered the 'extended universe' is now non-canonical to the overall Star Wars story.
Disney had announced several months back that most novels, comics, and video games would be considered part of the unofficial, unvisited part of Star Wars.
Disney further said that the Old Republic part of Star Wars will not be explored in any way. This means that Star Wars: The Old Republic and Knights of the Old Republic are their own stories.
