These days it seems that gamers are spoiled for conventions, at least if they're anywhere near some metropolitan area. PAX Prime, PAX East, EVO, Indiecade, and others such as Comic-Con are enjoyed by fans and industry alike. GameStop Expo is a relatively new name to the game as they hosted their first convention only last year. Still, they are able to reel in big companies thanks to their brand.
This is a tradeshow which happens to have open admittance to pretty much anyone. According to Troy Bartel, president of GameStop, there will be 80 developers, publishers, and vendors present this year. The highlight of the event is that the PlayStation 4 is going to be showcased, which is a system that would otherwise be relegated to press-only events such as E3.
If you're interested in checking it out, then hopefully you live in or near Nevada. GameStop Expo 2013 is heading to Las Vegas on August 28th at the Sands Expo and Convention Center. Those with a PowerUp Rewards membership can apply their points toward an admission ticket (which otherwise costs $35).
