Hopefully a curved display should make them feel lighter since the weight/mass will be closer to your face. Reducing inertial forces for head movement.
The Vive with one (1920x1200)*2 per eye is a total of 4,608,000 pixels compared to a single 4K is 8,294,400 pixels. This does not tell us how many of those pixels actually get used though as pixels that fall outside the field of vision are usually not rendered.
Actually the Rift and Vive both use a pair of screens that each have 1080x1200 resolution (not 1920x1200), so in total they have less than one-third the resolution of a single 4k display (2,592,000 pixels compared to around 8,294,400).
As for making the headset feel lighter, it's possible a curved display could help a bit, but you could just as easily position two individual screens at an angle for a similar effect. A single curved display might also make it difficult to adjust for IPD (the distance between pupils) which varies from person to person, since someone with a wider IPD would be closer to the edges of the screen, likely putting them out of focus, and the same would go for those with a narrow IPD. With two individual screens, or one flat screen, that's not a problem.
Also, as far as their mockup designs shown here go, the headset would probably be rather uncomfortable for extended use, since unlike all of the current major consumer headsets, there's no support on top of the head. The Rift and Vive each have a strap over the top, while the PSVR has a design that suspends the display from over the forehead, shifting much of the headset's weight off the face and onto the head. Despite the PSVR being the heaviest design, it's been widely said to be the most comfortable because of that. The renders for this headset don't show anything to transfer weight over the top, which might look nice in concept art, but probably wouldn't be very practical or ergonomic (the same goes for the white cloth, which would get discolored pretty easily). Going forward, I think we're going to see more designs closer to what Sony uses. The Windows 10 VR headsets that Microsoft revealed the other day use a very similar head mounting system to the PSVR, and I suspect Oculus and HTC will follow in the next versions of their devices.

No track record. No demo. I consider this vaporware, until proven otherwise.
I kind of agree. At least when Oculus announced their device, they already had working hardware to demonstrate, rather than just some CG renders. They were also announcing something that was relatively unique, since the only other consumer VR headsets at the time had narrow fields of view, imprecise tracking and practically no official support from game developers, and the VR field had been largely stagnating for many years. This guy, on the other hand, is coming into a market where a number of other, much larger companies are already developing similar hardware, and yet he's hoping to have a premium device intended to be better than the others available in a year. The timescale seems a bit too optimistic, and by the time such a product would likely launch, the specs would probably be nothing special compared to what other companies will be offering.
