I was really hoping SC would have a Linux Vulkan client ready at launch so that it doesn't get backburnered like every game.

It's the same principle with VR. When you've got a thing that affects this many people and a thing that affects this many people, you have to prioritize the thing that affects this many people. I think you'll find that's true in just about everything, not just video game development, just in life. It's literally a personification of 'the needs of the many outweigh the needs of the few'. So it's just what has to be. So VR will come, Linux stuff will come, or not; we have to prioritize what affects the majority of people first.
