I know the whole idea of the return of revan and an army of revanites is a good story line and all but if you played the game long enough you should have seen problems in that story line. For starters there is a quest on dromund kaas that you can destroy the revanites and on the flashpoint "The Foundry" you kill revan at the end.
so how does revan return with an army of revanites if the revanites are destroyed and revan is dead
