Well, the OLED Switch is officially out now so I don't think they'll make a successor to the Switch for another 3-4 years. We're in the middle of a chip shortage so it'd be difficult for them to make one right now.
Windows 11 was originally supposed to be a huge update to Windows 10 but for whatever reason, they decided to make it another version and that decision was made within the last 2 years so I'd also agree that it was rushed.
