Glyph, currently fundraising on Kickstarter, seems like they're taking a swing at the theatre-replacement headset. Instead of an immersive 3D virtual environment, their focus is high-resolution displays.
The Glyph looks interesting, but it only shows 1280x720 per eye.
I don't really understand how the 'virtual retinal display' will affect the viewing experience, but there are only 2 million pixels total, split between two eyes.
The consumer rift will be at least 1080p split between eyes, which is 960x1080 per eye — slightly more pixels per eye than the Glyph.
