Anakin would last about a minute I'd say...after running like a b*tch (after 20 seconds of fighting) Revan would throw that massive ingrown townail he's had since Taris, at Anakin and melt it over Anakin's eyes. Anakin would claw at his eyes in vain until eventually accidently stabbing himself in the head with his lightsaber in attempt to remove the melted nail.
Well lets see, Revan seems to be a defensive fighter from what we have seen of him, in the FMV he doesn't go all offensive and attack the Jedi, he waits for them to make the first move.
Anakin uses aggression in his fights. Anakin would probably end up making a glaring mistake, then BAM!
Anakin lasts about fifteen seconds.
