Most people don't care. And that says someone who replaced his Windows XP when Vista was the newest shit on the market (I also had a Vista laptop back then). With every Windows version people argued and posted about The Year of Linux Desktop. If you are talking about number of users, then Linux on Desktop will not dethrone Windows in 2024. Most people don't care or the switch is painful in many ways. Don't get your hopes too high. My following argumentation is critical, but I am a Linux fanboy. Have that in mind.
KDE/Gnome reaching stability and usability
What exactly do you mean by that? KDE and Gnome reached usability long time ago. However thanks to Wayland the stability got a huge hit, plus KDE was always a bit wonky in regard that. But otherwise these are great desktops with good usability for a long time now. Way better than what Apple or Windows has to offer.
Windows 10 coming to EOL
This has never mattered. Most people just switch or buy next Windows version.
.Net cross platform (in VSCode or Jetbrains Rider)
This is not new in 2024, or did something happen here?
Better LibreOffice/Word compatibility
Better than what? Than the previous version? This is always the case and people don't switch from Windows to Linux because of that. After all, the application is available on Windows too.
... will be ... before end of 2024 ...
Will be remain to be seen if this is true. If there is one thing I learned is, don't trust estimation when software will be finished.
NTSync coming in Kernel 6.11 for better Wine/Proton game performance and porting.
This has no impact on Proton, but Wine as far as I understand. Proton already has an alternative that is similar to NTSync. So from performance standpoint, it has no impact on Steam games.
