Pokemon tournament at PAX

There's supposed to be a Pokemon video game tournament at the Penny Arcade Expo on Labor Day weekend (Sunday, 11am-4pm). Rules haven't been posted, so who knows what the format is supposed to be. It'll be in the handheld lounge, so it's unlikely that it will go through Pokemon Battle Revolution.

Depending on the format, I'll play. 5 hours of Pokemon play? PAX has almost too much stuff going on to be tied down for that long.
