I figured out what happened to Revan the other day
spoiler: [joke] so after hearing from Bastila that he was going to be a father he skipped town and "lost" himself in Nar Shadda, got himself a flop house, and started frequenting the pazzak dens and started dating a Twilek dancer. The reason nobody has found him is because he can mask his presence, that combined with being on the smuggler's moon (which is hard to focus one's self iirc) is why the crew could never find him again. [/joke]
It's so obvious
