Geoff Keighley, a canadian video game journalist, said throught his Twitter account:
How far into the future are the VGAs going? I just reviewed a piece that says “coming 2013″ at the end.
Let’s think about this one, to be revealed 3 years before the release must mean this is a huge game, one which will set an unprecedented amount of hype. Honestly, the only ideas we can formulate in our heads is GTA V or Half Life 3. They are the only games big enough for an event like this.
