Obviously though because of TOR we wouldn't find Revan, we'd run into certain 'obstacles' preventing us from getting to him but we would eventually learn where and how a couple of hundred years later.
The only problem with that potential KotOR III plot is that
T3 went with the Exile in the Ebon Hawk to find Revan, after TSL, in the Unknown Regions.
