GPS-only RNAV STARs (Standard Terminal Arrival Routes) have been in use for some time.
The "next gen" technologies referred to in the article involve a lot more than just GPS improvements (such as WAAS and publishing more RNAV GPS approaches annually). They include new ground radar for automated taxi operations, a replacement of traditional transponder-based aircraft separation, redesigning ATIS and weather reporting, and an overall push to standardize all ATC data -- ultimately getting more real-time data into cockpit avionics.
