This is pretty cool if you live close to San Antonio...I would pay the money and go just to play Dead Space 3 early

They need to have one of these in CA or NV

GameStop has posted some more details about its upcoming GameStop "EXPO." Usually, this event is reserved just for store managers and associates, but this year the US games retailer is opening it up to the public (the public, in this case, meaning PowerUp Rewards members willing to pay $35, or a $100 VIP fee).

The Expo runs from 11am-4pm on August 29 in San Antonio, Texas, and during that time attendees will be able to play games like Call of Duty: Black Ops 2, God of War: Ascension, and Dead Space 3, among others. Devs will also be on hand for a number of games, Nintendo will show off the Wii U, and there will be giveaways, autograph signings, and lots more.

Sounds like a fun afternoon in San Antonio. Though if it's anything like our local GameStop, look out for the mom trying to get her kid to leave without a game, the salesperson selling magazine subscriptions, and that guy in the corner who really, really wants to talk about how great Jak 2 was.
