I don't think there is any way around the hardware requirement if you want any kind of decent graphics experience. You need to calculate each scene twice (once for each eye), otherwise you're not going to get stereo vision.

And unless you want to view your minecraft world in 3D, that's going to result in hefty hardware requirements.

Definitely. The target specs[1] they announced are pretty beefy: NVIDIA GTX 970 / AMD 290 equivalent or greater, Intel i5-4590 equivalent or greater, and 8GB+ RAM. However, now that there is a target that means that tech will only continue to get cheaper/better from this point forward, so the longer a consumer waits to purchase the Rift the less likely it will be that they need to upgrade their hardware to use it.
