Today's Nintendo Switch livestream revealed that Star Wars: Knights of the Old Republic will be released for the Switch on November 11.
Skip to ~44:48 for the announcement.
Clearly this is not the 'Remake' version coming for PlayStation, PC and Xbox, but rather a straight port of the Bioware original from Aspyr games. You can pre-order it from the Switch store if you think digital copies might run out, and/or if you'd prefer Nintendo to be gathering interest on your money, rather than yourself.
