there is a leaked image of ps5? can you post it here. i didn't know.
about buying 4k tv this year. i recommend you to wait till next year to get a 4k tv because next year, many tvs will equipped with hdmi 2.1 connections that can support 4k120 and some might come with 4k120 broadcast tuners built in i think.
this year, only a few 4k tvs come with hdmi 2.1 connectors and even then, i don't know if these 2019 4k tvs model support native 120 fps sources.
