As we reported a little while back, Blizzard will be in attendance at the sold out Penny Arcade Expo in Seattle, Washington this weekend, and Crygil has posted on the forums that they'll have everything playable that they had at BlizzCon: the new Diablo III Monk class, the Cataclysm expansion, and the Starcraft II singleplayer campaign. Somewhat strangely, they don't actually say that the Cataclysm expansion will be the same starter zones that we played at BlizzCon -- they may actually have some of old world Azeroth open and playable. But on the other hand, they'd probably announce something like that if it was happening, and given that they'll have a smaller setup than BlizzCon, we don't imagine there'll be anything really new there.
In other WoW news at PAX, our friends at The Guild will be screening the entire season 2 on Friday evening -- Jeff Lewis and Sandeep Parikh will be there, along with producer Kim Evey and Wil Wheaton (Felicia is headed off to Dragon*Con this weekend). Unfortunately, the screening is during the Friday evening concert, and so you might have to miss Anamanaguchi, Metroid Metal, and MC Frontalot. My favorites Jonathan Coulton and Freezepop are playing on Saturday night, though, so you can fit in both of those if you like.
Should be fun. We here at WoW.com spent our travel budget on all of the action at BlizzCon (and by budget I mean the shoes AOL gave us to walk to Anaheim last month), so we won't be around at all, though our colleagues at Massively and Joystiq should be there and covering. If you're going, first of all enjoy yourself, and second, take pictures and send us reports if you see something cool. You lucky ducks.
