It was when the DK2 first came out that I realized VR was not the slam dunk it is often portrayed as. The DK2 was bought by many people, many more than the DK1. And once all of those customers started posting feedback on the internet it became clear that motion sickness was still a huge problem. And motion sickness will not be resolved with higher frame rates or lower latency as most of us believed prior to the DK2. Oh well.
