Well no, Revan technically destroyed the sith and at the same time made them stronger, but he did it unintentionally by turning back to the light side. The Sith'ari has to be Bane but he wasn't a perfect being. It could be Sidious but seeing as how there were only 2 sith at a time, destroying your master doesn't exactly constitute as "destroying the sith and making them stronger".
The Chosen One and the Sith'ari are two separate prophecies.
The Chosen One Prophecy is the "One who will destroy the Sith and bring balance to the Force."
The anarchistic Sith'ari Prophecy is the "Perfect being who will destroy the Sith and rebuild them to make them stronger."
The Chosen One Proph. can only be Anakin in killing Palpatine on the Death Star, or Luke or Leia in finally killing him in Dark Empire.
The Sith'ari Proph. can only be (from what I see) as either Bane or maybe Kaan for unleashing the Thought Bomb and destroying the then current disorganized Sith. Or perhpas Anakin again for killing Palpatine, only to result (through the Butterfly Effect) in the Sith once again rising to take control under Darth Krayt, though Legacy is still unresolved.
Originally posted by Darth SexyBegging your pardon, but...what? The last true Sith was Naga Sadow, but those are semantics.
No, even Lumiya states that he wasn't a true sith, that he was a clone who just acquired all the knowledge and power of the first Palpatine.
Are you saying that Palpatine's bodiless spirit, which spent seven years after Endor getting into a clone body he had prepared beforehand on Byss with Sate Pestage's help, using a similar Sith technique he had used on Bevel Lemelisk like 7 times, was not actually a Sith? Are you saying that that Palpatine wasn't even Palpatine? Or are you getting Dark Empire confused with the cloned Thrawn?
Revan's probably pretty young, given that by the start of KotOR, Trask Ulgo says something like, 'we haven't seen your kind or potential in a raw recruit in years' implying that he was pretty young. Most likely in his twenties. I really don't see why you would consider him the Sith'ari. His destruction of Malak's order didn't make the sith stronger, and he wasn't leading the sith when he destroyed them.
