E3, otherwise known as the Electronic Entertainment Expo, opened their doors to attendee and media registration yesterday. This year’s expo will be held at the Los Angeles Convention Center on June 15-17. Also, while not open to the public, expectations are that this year’s expo will be more like earlier years, where the booths are larger and the retail sector has more leniency in who they can send. Previously, G4 TV has always covered the expo well, but E3 is expanding their presence into prominent social media vehicles, too. This year, fans will be able to follow the action online with Twitter, Facebook, or on Flickr.
