Yahoo! is reporting that, in the race to claim E3's crown, the Game Developer's Conference has announced there will be more than twice the space on the show floor next year. From the article: "When GDC was last in San Francisco in 2005, the show occupied the three floors of Moscone West. For GDC 07, the organizers reserved both Moscone West and Moscone North. With the Moscone West show floor virtually sold out, the organizers have now additionally secured the keynote hall in Moscone South in order to convert Moscone North into a second dedicated show floor. This will allow the GDC to accommodate the voluminous requests coming in for exhibition space and to include fresh exhibitor opportunities, such as the all-new Game Demo Theater." With PAX, GDC, GenCon, Leipzig, and others all lining up to be 'the next E3', is it too early to place bets? Will one event reign supreme, or is the E3 cake going to be shared by all these groups from now on?
