After Valve's Gabe Newell was honored as a Pioneer at the GDC Awards, I asked him to predict gaming's future and to offer more Portal 2 teases, a Half-Life 2: Episode 3 update and Pokemon tips. My success rate: 50%.

Notes: The "John" who Newell refers to is John Carmack. The Portal 2 thing he refers to is the blue-screen "crash" that occurred minutes earlier when he was accepting the Pioneer award.

This is one of a series of Kotaku video interviews with many of the award-winners and special honorees from the Game Developers Choice Awards. Check out the rest of our GDC Backstage clips, featuring the creators of some of the world's best video games.
