The dirty little secret here is that Nausea isn't just caused by hardware alone, but also by software. There are a significant number of things software can do wrong which makes the improvements on the Rift redundant. For example, jumping from large heights, moving too quickly, stopping too suddenly, poor clipping artifacts, inconsistent lighting, and much much more. OVR can talk all day about how they've 'fixed' nausea, but until they fix the games people want to play (which aren't going to be optimized for a pretty small subset of hard core gamers that have one of these), they're going to have a hard time selling the HMDs. That all being said, I have one and love it dearly and try to get everyone I know to buy one. Realistically though, it's going to take awhile to fully launch this device.
