If it happens, great, but at this point, it doesn't exist.
Also, in terms of canon... stuff is canon until it isn't. There are many examples of things in Star Wars that were once canon but aren't any longer because of something that was released afterward.
In the future, there is a possibility that SWTOR may be bumped off the canon list... hell, there's a possibility that The Knights of the Old Republic era could be bumped off entirely. We just won't know until it actually happens.
After all, the entire post-RotJ EU is being wiped out by the upcoming Sequel Trilogy and no one saw that coming until it was announced.
