My guess is that Oculus gave them money and they signed contract similar to one that MS had for X1 indie devs where game had to be X1 exclusive first (if i remember correctly). Yes those games will come to Vive to but people don't want it 6 months after Vive release.
Sounds about right. Orth for the money.
But at least Adam Orth said it isnt timed, so shouldnt it come to the Vive a at Vive release?
I'm not trusting that statement when also looking at the other ones. Seems that it is, but also it doesn't seem like there is a massive difference between VR and standard in the first place. Vorpx will eventually get Vive support, as soon as they can get when which will be when it releases. That will probably work out about the same
