Hopefully if all BIII launches are on schedule will get full L1C and L2C coverage by 2023 which would allow cm and sub cm accuracy with dual channel receivers to be used everywhere.
Especially since GPS and Galileo decided to play nice and the compatibility was agreed upon we will be getting better and better GNSS for general purpose use.
