I don't know if anyone has seen this or not, but here is the GenCon schedule dl this year. The first SWM event is at 2516 on the spreadsheet, and the gaming group is Wizards of the Coast. There's 3 events so far, including the GenCon league.

There is an entire section of the forums here dedicated to GenCon 2008, and that's more where this thread belongs. Besides that though, there's already a couple other threads in that section with all of this information. There's actually quite a few more than 3 events. Anyways, I'm going to lock this thread, and anyone looking for further GenCon '08 info should look in the appropriate section of the foums here.
