I didn't even know there was an internet presale this early (usually it's the day before tickets go on sale IIRC), but I just found out and the password for the WWE sale is DANNYJ. Hope this helped and that this hasn't already been announced here, I looked but didn't find such a thread. Go to fordfield.com and click on the WM23 logo. It's supposed to end at 10:OO PM tonight.
SD/ECW has a house show here on the 30th at the O'Dome (which I'm too poor to go to, probably). Announced main is Batista and Booker in the cage and Kane versus Kennedy and MVP in a handicap match. As ridiculous as it sounds (and so cliche)
