I mean we already discussed it (with some people arguing rumours were trash and should never be listened to), every leak/rumour back in late 2020 early 2021 pointed to a significant upgraded model by the end of 2021, and we got the OLED, which is superior to the original Switch (post 2019) in every aspect, except for the SoC. So I guess they reached a breaking point where they were like "okay nevermind, scrap it" and they released the OLED without the power upgrade.
And then it was already too late to release a new model. I mean at +120 million units sold, you don't wanna divide your install base.
