We still have to wait for the exact FoV, and the eye tracking seems interesting but it doesn't seems to be better than the Hololens, and won't be from the 2018-2019 Hololens.
Wait, the Hololens has eye tracking? That's interesting, I'd never heard that before.
Anyway, I think the main innovation Magic Leap seems to be pushing over its competitors is its multiple depth of field display. It'll be interesting to see how big of a difference that actually makes in practice.
No HoloLens doesn't have eye tracking. I think they're saying the device as a whole doesn't seem to be better than HoloLens. Which I might agree with. The form factor may be stranger though, which would be an accomplishment.
