I've heard that the Piano series will have G2 versions as well, possibly by the end of this year. New enclosures (tiralit composite material first used in the Agoria), binding posts and stands/bases are in order. I believe the crossovers and drivers are the same. Insofar as the sound goes, I heard from someone who is not a Tidal dealer and he reported that the sound was denser and more dynamic (Contriva G2). Can't imagine that the Contriva extenders would be necessary.
