There's no mystery about that really - RL benchmarks show that you mostly need 3xGPU to run the game at the same frame rate in 2160p compared to 1080p with same settings. If any of the consoles is to have that much juice, yeah, then they can (in theory) run at such res natively (with same settings).
My bet is (if any of MS/Sony intend to increase internal res, which I somehow doubt) 1920x2160p anamorphic - this is 12.5% more pixels than 2560x1440 with less artifacts when upscaling to 4K UHD.
But then again, I don't expect even PS5 to render in 4K native, if they intend to have similar jump in visuals as in 7th to 8th gen, and not spend a lot of GPU resources in transition from 1080 to 2160p.
