IF they decide to proceed with the cracks existing in the Stage 2 nozzle, that is. They were going to decide tonight, but haven't announced yet. http://www.spacex.com/press.php?page=20101206

Now, you have 2 small cracks in a low-stress, non-mission-failure part of your ship. You're on the pad. I like SpaceX's approach: start seeing if there's something critical that they're missing elsewhere, and see if they can just trim out that portion of the nozzle and launch anyway, because that amount of efficiency isn't needed on this mission. Be interesting to see whether it's Go or No Go for Wednesday, or if they hold off a day or so.
