Oculus Rift Upgrades to Four Sensors

Check it out! Oculus finally did it! We will officially have four sensor capabilities on the Rift, which will undoubtedly make it the single most accurate VR headset this generation as well as, when released, the sole inheritors of the improved peripheral technology available through Oculus Touch. We'll see, but it looks like the VR wars just had a big technical breakthrough.

I still have two concerns about this. The number of compatible USB 3.1 ports required, there up to 5 now? or is it 4 high speed and 1 regular 2.0 port for the HMD? In either case that's allot of USB ports. My second concern would be the cables. That's allot of, i would hope, long USB cables. Not only is it a tripping hazard for room scale but you also have to deal with them, Though there not much of a tripping hazard with the Omni.
But at least now Touch owners will be able to turn around and not lose tracking. I hope Valve comes out with the ability to add more lighthouses to reduce occlusion as well I would buy him in a second.
I also hope it can support multiple different layouts. It's going to be stupid if you have to have them laid out in a specific pattern. I would think that a pyramid shape would actually be the most accurate: 3 of the cameras installed slightly below head height in a circle (60, 180, and 300 degrees) and then the last one installed overhead for a birds eye view.

But an officially supported five-port USB 3 card costs about $30. Three extra cameras will cost about $300. So it's a minor issue unless your PC is out of PCI-Express sockets. Two lighthouses is a fundamental limit of the current design, since the headset can't tell which lighthouse is illuminating it at any time. You'd have to start flashing them with a coded ID or something to support more than two, or reduce the scan rate even further (AFAIR, the two lighthouses currently alternate, so only one is illuminating the room at any time).
