A video posted by GameSpot offers the entirety of John Carmack's Game Developers Conference presentation on what's going on at Oculus. As previously noted, a lot of this focuses on how the future of virtual reality will involve mobile devices. The description reads: "The dawn of consumer mobile VR is close. Come hear the technical details of making mobile VR a reality; techniques and strategies for maximizing the quality of your VR games, applications, and experiences; and thoughts about the future of VR, including what it means for the mobile ecosystem."
