It depends actually, since they change it from exchange matches into tournament base the anime still has room opened for Rating Game between Rias and Sona.

Be noted, Saji may have all 4 Vritra Gears now but no signs of Vritra being awaken is shown yet, this might still lead to a potential match between Rias and Sona.
