If anyone is interested, might be able to get the dev kit and give it a whirl with UE4 ?
Good luck! 
And I thought Valve had put VR hardware on the back burner… this is incredibly intriguing, considering their hardware (as of Steam Dev Days in Jan 2014) was considered better than the contemporaneous Oculus Crystal Cove prototype: http://www.trustedreviews.com/news/valve-s-own-virtual-reality-headset-is-mindblowing-better-than-oculus-rift
I’m interested to see what games/apps they have running on it, how much Epic is involved (like they were with making the Showdown prototype for Oculus Crystal Bay).
I’m cautiously thinking we mere mortals won’t be able to buy dev kits any time soon, but hopefully we’ll hear a lot about this next week!
