There IS a hacked PC driver recently released. And you can bet that if the Oculus gets locked down (doubt it), it'll be hacked even faster.
The reason the Xbone controller took some time is cause no one actually CARED about the Xbone controller. The 360 controller, DS3, and DS4 controllers all worth with PC already. The Xbone controller adds no functionality over the already existing ones. If the Oculus is locked down, people WILL CARE (Oculus already has a large following and it's not even out), and will put much more effort into hacking it.
