If you want 4K120 capability you need the current BX/CX, or the 2021 C1/G1/Z1 when those come out later this year. Or you could wait for the Sony A8J and A9J series for 2021, too (or the X900J/X950J which aren’t OLED but very, very good full-array local dimming LED panels). Note that Sony and LG use the same panels for their OLEDs and there is no 70” or 75” size. It goes 48”, 55”, 65”, 77”, and sometimes 83” or 88”. However, I don’t think 4K120 is going to be super viable for these consoles for most games. There will be some stuff that can “do” it, but I think a locked 60 will be plenty for pretty much everything. I bought a Sony X900H this year and it’s been an adventure with 2.1. Sony seems to have a problem with actually implementing the promised features. It also currently cannot pass Dolby Vision AND 4K120 signal at the same time. It is, however, still a great TV and has awesome PQ for the price. Also, if you use a receiver, the new models have a Panasonic chipset that have issues handling the Series X 4K120 signal WITH HDR. Without is fine, but the whole 2.1 thing has been a bit of a boondoggle so far because these companies released products before the specs were standardized and before there were actual devices to test with.
