Intel's Z790 motherboards will be launching as the flagship 700-series platform designed for 13th Gen Raptor Lake CPUs. These motherboards are expected to carry some new I/O features that will give some reason to get them over the existing 600-series products but we can assure you that if you are on a Z690 motherboard, you're good to go.

The Intel 13th Gen Raptor Lake CPU lineup is coming later this fall and the blue team will be ready to support it not only on the existing 600-series motherboards but also on the next-gen 700-series boards. Now, these boards have already been revealed and will come in three flavors, Z790, H770 & B760. The H710 motherboards are seemingly canceled as the H610 boards will take their place and continue to be offered in the entry-level segment.
