It certainly would not be a Penny Arcade Expo without The Behemoth, and PAX East is no exception. We've just been given the juicy details on what the studio's setup will entail. I had to shove a few kids and old ladies out of the way to get the info, but I think it was worth it.
Booth #550 is set to have a new playable build of BattleBlock Theater that contains Story mode levels and co-op on two separate two-person arcade cabinets. There's also four-player Castle Crashers on The Behemoth's PlayStation 3 arcade cabinet.
Outside of the playable goods, look for plenty of merch, giveaways, and Dan Paladin signings (1-3 PM each day). Think of the poor man's hand before you go too crazy with the requests.
