Oculus Rift Future Possibilities

Oculus Rift is a virtual reality headset which aims to impress its users at an affordable price. While some consumers and developers are testing the experience on the first devkits, there are more planned for the future. During Gaming Insiders Summit, head of Oculus VR Brendan Iribe detailed his plans on the future of their device. Current Oculus Rift devkits have 1280x720 resolution, but there are already 1920x1080 prototypes and there are plans to reach 4K resolution in the future. He also said that latency has been reduced a lot and no longer causes him to feel motion sick:
"I've gotten sick every time I've tried [Rift]"
"In the last couple weeks, I've tried a prototype internally where I did not get sick for the first time, and I stayed in there for 45 minutes."
Another future possibility for Oculus Rift was mentioned in an Engadget interview by John Carmack, CTO at Oculus VR. He has also mentioned that 4K is a future target, but considers improving head tracking a more important task at the moment. Another feature they are looking to implement is adding a separate system-on-chip to allow running 3D applications on Oculus Rift without being tethered to any additional hardware. Of course that would not be a replacement for a more powerful PC, only a complimentary feature for lighter tasks. It will be interesting to see which features will be ready by the time of the official Oculus Rift launch.
