The above is the navigation specification (see PBN Manual) for RNAV(GNSS) approaches. They are currently titled as RNAV(GNSS). ICAO have an extended transition period to retitle RNAV/RNP procedures.
The concept of PBN was essentially to rationalise the number of navigation specifications and simplify the whole RNAV/RNP issue. Probably not surprising to see it going the other way. Standby for ARNP and RNP(0.3) specifications next year....
