Having worked with VC's before, there isn't always a clear domain understanding of the problem they are investing in. Additionally, once funding snowballs, later investors can incorrectly assume due diligence has been taken care of by earlier investors.

I would expect that we've seen what MagicLeap is targeting in both Google Glass and later Microsoft HoloLens. So conceptually the systems and optics are proven at some early stage. Instead of projecting into a lens that is then reflected into the eye, they claim they are projecting directly into the eye. Either way the optics should be similar. This means that as with any AR (instead of VR) system, they will not be able to project the absence of light in a brightly lit environment. (Creating shadows/darkness should be impossible)

Probably similar to HoloLens, very different from Glass.

There are ways to hard-occlude, e.g. LCD mask, but might be punted til a later version.
