Kotor isn't canon ATM, but unless they put something out that directly contradicts it I'd give it decent odds of being brought over.
They aren't going to un-legends Legends content outright.
Anything in the pre-Disney era outside of the material directly created by Lucas himself (The 6 films + The Clone Wars) is non-canon.
Everything post-Disney such as Rebels and the Marvel Comics are canon.
They stated elements may be incorporated in future new canon material, but Legends content outright will not be canon.
A new KOTOR game could come with elements of the olds ones and be canon, but the old games are Legends and non-canon.
Great OT. Might I suggest giving a little love to SWTOR? It might not be cannon, but it is still a Star Wars MMO.
Anybody pick up Heir to the Jedi yet?
I got it yesterday and plan to dive into it today. Pretty darn excited for it.
