Hmmm.
Given what I've learned elsewhere, Luke has just now surpassed his dear old dad. However, it's a close enough fight that Jacen's on his own vs. Kenobi and Soresu.
Fortunately for Jacen, he's not a kamikazee attacker, and Soresu is a super slow way to fight.
So Luke vs. Anakin will finish first, and Obi Wan then dies.
