There's been alot of talk about VR headsets recently from many companies, Sony, Razor, Samsung and Oculus, and it seems that the Oculus Rift has taken the limelight so far, but after hearing talk about what Valve have been up to such as the QR code room, Oculus needs to be watching their back.
One of the big talking points around VR headsets is how we are actually going to control the environment we are immersed in while wearing whatever headset we choose, but it looks like Valve have been able to take their work on the Steam Controller and made it work with the headset. I think we are going to hear much more about this system and it's going to be interesting to see where the people's interest falls as we get closer to all of these systems releasing final versions.
Perhaps Oculus need a partnership to bundle a contorller system with their headset
Razor had some minor updates to their modular approach for developers, but I don't see this as a major competitor to Valve or Oculus as it will take a developer with a large budget to come along with something above and beyond what is almost ready to ship from the aforementioned.
And of course there's still plently of scope in the VR headset world for accessories
After seeing some coverage of Sony's Morpheus demo too (see below), I really think the race to these products coming to market is going to be exciting. Again it looks like because Sony have their own controller support, they are in a really strong position to deliver interesting experiences. Maybe Oculus got out there too early with an unfinished project, or maybe it was important for people to learn at this stage, so we could get to where we are today.
