Rumors were already running since early 2020 about the arrival of an improved version of the Nintendo Switch console with Ultra HD 4K display, but in the end we were only entitled to "only" one model, the only one of which, or almost, evolution consists of the presence of an Oled screen instead of an LCD specimen.
Nintendo Switch 4K Kit from the developers
However, a dozen developers say they have had a Switch 4K development kit for a while (source Bloomberg). They even expect their 4K games to be released at the end of 2022, suggesting that Nintendo is still planning a further improvement to its console for the near future.
