I'm thinking it will be a 3 step fight. First will be Shaidar Haran and Rand fighting with swords made of the True Power and Saidin, respectively, as was the fight with Ishamael during the Great Hunt. Second will be True Power vs Saidin abilities. Third will involve one massive attack that will reshape the world on Rand's part. On that will kill Haran, reseal the Dark One, and leave Rand on the brink of death as his channeling ability is burnt out.

Try about 10x that at least. The last book was almost 300k. The books average 150-225k words. Sanderson had to break the final book into 3 parts because, even cutting it down, he was breaking 750k words. He didn't want to leave anything Jordan had planned out, and felt that cutting it down would be disrespectful.
