Those hardcore simracers who invest in things like 3 monitors probably will, for the rest I doubt that. Most competitive sim racers I know still drive with a single display. Oculus adds new problems as well, for example high response times compared to a gaming monitor, motion sickness issues, etc. There are still too many question marks to predict if this becomes a mainstream product. My vote is also to focus on what is essential: make modding easier, work on Steam integration, etc.
