New Viewfinder from Nikon?

Guess Nikon is working on a new viewfinder technology that allows a tiny display screen to be viewed right inside the optical viewfinder itself. Apparently, the photographer has the choice to switch between the optical image and digital display. One interesting point would be the ability to enable a wide viewing angle whenever the subject is zoomed in. This wide preview mode can be accessed through a button located near the lens mount, and chances are such technology will make their way on DSLRs instead of low-cost point-and-shoots. I wonder when will this patent application be approved .
