In the 757/767 we did VNAV approaches. Basically, you plugged in the descent gradient into the FMS and it made a non-precision approach just like an ILS.

There's some newer technology out there flying RNP (required navigation performance) approaches. These are basically RNAV/GPS type approaches where the onboard navigation system monitors the quality of the navigation track. In the future...I think you will see alot of RNP type navigation.
