I don't see Hogan having to "Hulk up twice" to get the win. Here's another way the match could go down:
I just simply can't imagine a scenario where Batista could cleanly pin a prime Hogan completely within the rules.
So, my scenario would be that Dave would be in control, but continuely fail to put Hogan away for the first fall until he got frustrated and started to beat Hogan with a chair or something causing a DQ after a long first fall. Then, with Hogan weakened from the illegal beating, Batista would just destory him and run through him to take the second fall and even things up. It would be in the third fall where Batista would still be dominating Hogan who would still be selling the earlier beating until, just as you think Dave's gonna get the finish, Hogan "Hulk's up", points, punches, boot, legdrop, etc. and gets his first actual pinfall of the match to win the final fall and advance on.
