RFID at Item Level Reaching Tipping Point

For years starting in 2000, we predicted the near approach of common item level RFID use  in retail.    It eventually became much more common at the pallet and case level in some industries, for supply chain transparency.    In Retailwire quoting GS1:

" .... More than half (57 percent) of the retailers surveyed in the "2014 GS1 US Standards Usage Survey" reported that they are now implementing item level Electronic Product Code-enabled radio frequency identification and an additional 21.1 percent plan to implement the technology in the next 13 to 24 months. ... " 

Tipping point perhaps, but still think the common use of this is at least some years away.
