Far more important as resolution, will be the apparent field of view (AF) of such a device.
Sony's field of view is only 45°.
Have you ever watched through binoculars or telescopes equipped with eyepieces with only 45° AF? It's like looking through a barrel with the typical big black circular Border.
But if you equip the same telescope with a 100°AF wide angle eypiece you'll get the feeling of looking through the window of a space ship! There are no boarders, no tunnel view, just a free floating image in front of your eyes.
The prices for these optics are very high, because it's very complicated to generate a sharp image over the entire field of view so close in front of your eyes.
The SENSICS solution from louisv offers 120° horizontal and 45° vertical.
This is already a very good benchmark.
So if I would have money.....
