Lucasfilm declares all Star Wars games, comics, novels and other expanded media non-canon
[...] only seven products in the Star Wars universe that should be considered canon; the six films, along with The Clone Wars TV show.
On one hand... this makes SW:TOR non-cannon.
On the other... it makes the Thrawn saga, KoTOR and KoTOR II non-cannon.
I still wonder why the new movie trilogy isn't the Thrawn saga.
I have little hope of them making anything that could surpass those books.
