eh, not always. I was in the VR eye track thread last night. And everyone is throwing around the term, "1st gen VR hardware wont have eye tracking", it will come in the "2nd gen hardware, in a few years". This was repeated over and over. Then you see the thread title here, and it says "HTC unveils Vive Pre, its second-generation VR system " and It throws you for a loop. New name, 2nd-gen. Obviously I knew something was up though, so I went back and read the article. But, I mean its not unheard of for devkits to be out a year or 2 in advance of the actual hardware release. And I could possible see an actual Vive 2 out within that time frame.
