I saw your post in the news section. Don't worry, people are buying Rifts so fast their payment server couldn't take it. Palmer even tweeted to say more people were buying than they expected.
Oculus founder Palmer Luckey seems to be having a pretty good day so far. "We sold through a lot faster than we expected," he told Polygon. "I can’t talk about numbers, but we sold through in 10 minutes what I thought we were going to sell through in a few hours, which is one of the reasons the site was beginning to buckle."

All those people will be hungry for content. You should also be able to stick to your principles of creating a high quality PC experience and create a Vive compatible version later this year so everyone with a PC VR system can buy it.
If you set the benchmark for high quality PC rendered experiences you will become the go to provider for them. As time goes on your market will only increase.
