My take: I think there will be a PC VR Rift 2, just that internally they aren’t all on the same hymn sheet on when that should be. Business-wise it makes sense to do stand-alone VR, and some of the original Oculus founders will find that hard to adjust to.
There will always be PC VR, it’s just a $3000 PC to drive it means it can’t be mass market. The R&D will happen on PC headsets, and a lot of advancement will happen there first, but it might not be the bulk of the market.
Just like Volkswagon still have ‘Porsche’, Oculus will have a Rift 2 at some point, it just won’t be marketed or sell as much as a Jetta.
