This looks amazing, but I've always been put off VR by the bulkiness of the headset - I've got to wonder how it can be worn for long periods, and what that might do to my neck. Plus there's a risk of nausea and headaches, which would be pretty shitty if I dropped a couple of grand on a headset! Anyway, how realistic is it for VR headsets to be miniaturised, so they more resemble a pair of glasses? Or does physics mean that will never be possible?

You can go a fair bit smaller, but the primary size driver is the optics. Pancake lenses, which combine refraction with reflection, allow the depth to be much smaller while having similar optical power. However they cause image artifacts and have really poor light transmission, so it takes a good amount of R&D to get them good enough. A traditional refractive system, especially for a high-fidelity device, is a better choice for now than optimizing for size. That can come later.
