Yes. All my drum and percussion books are still using old staff notation. Not a single one is written in PR notation.
Future sounds, The New Breed, The Art of Bop Drumming, Syncopation, Extreme Interdependence, Creative Control, Conversations in Clave ... you name it.
So when I need to see a drum performance I need to see notation. Maybe the BBC Orchestra, London Philharmonics or other institutions have implemented PRV this year, but one cannot be too sure.
