That's an interesting question. I've not seen anything (at all) about VR in all the dev updates or FAQ. I certainly could have missed it if it was though.
My hunch is that VR will not be included. MAYBE it could be a stretch goal with added funding, but it would be best in my opinion if they focused their energies/money on the core game-play mechanics more than VR.
I'm not against VR, but I'd take a better running game over an added VR feature any day.
