So here we can see that the google glass can be rotated up/down and left/right, where in Explorer Edition only left/right is possible. This is one of the most wanted features by the glass users.
So in the above picture we can see that the battery will be placed on both sides for more battery, where in Explorer edition we got only battery on right side. This really increases the usage time of glass.
In this picture you can see the glass can be moved forward and backward to adjust the view.
So with some of these features we can predict that, a adjustable user friendly device,
a device with more battery for extended usage and heavy usage.
With all these features we can we can hopefully fix a custom glass as wanted.
These are just the things known for now, but there are still, 7 or eight pages to be relieved.
So keep you eyes open , ill be updating more soon.
