Hmm, this one is tricky since at 4K HDR10 at 60fps HDMI 2.0 is enough as we see with PS4. However when support for eARC will probably be there on PS5 (for Dolby Atmos passthrough for example.) It's an HDMI 2.1 standard but a lot of TV's already support it without having 2.0 for example the Sony AF9.
I guess it's best to wait for CES in 2 weeks and see what Sony will release on their next gen TV's.
