Well guess what, as of now they are no longer canon! During my scouting adventure to Wookieepedia, I discover a horrible news: Star Wars Canon have rebooted in April 25. Everything you know and love in the Expanded Universe got tumbled into a pathetic timeline called Legend timeline, or does not exist. EU is now the "official fanon" and this include your favorite games! Battlefront! Republic Commando (rest in peace, RC-1/207; Sev), and - sadly - any other versions of the Clone Wars. All that is canon right now is: Episode 1-6, TCW (shudder), and this new cartoon series based on around 4 BBY that REBOOT the origin of Rebellion. That is right, Starkiller no longer exist (why Disney?! Why must you butcher the original trilogy too?! I bet one galactic credit Ahsoka is in it in one way or the other). To me, this is like Stockholm Syndrome, where they force horrible things in and all you can do is accept and live with it. Do tell me what you think as I cry myself to sleep now....
