It looks like the Game Developers Conference is making
a play at becoming the next E3 as the show will double in size next year. While the show will still centered on the developers it looks like they are adding space for exhibits and demo space.
I see why they would want to pick up E3's slack but the GDC was really the one place that seemed free of booths and exhibitions. I'm interested to see who is going to show up and if the GDC evolves into the circus that E3 was. Personally my money is on CES since they already have the infrastructure in place to support something but I have a feeling it's going to take a few years to sort everything out.
