This surfaced this morning...from Gizchina:
If true, W12 will be stunning...so many new features. The taskbar, Start menu, explorer...all revolutionary.
The dynamic dark mode looks gorgeous.
To be clear, MS hasn't confirmed anything, and this is a concept video, but:
"The highly reputable concept creator, Addy Visuals has come up with something new that shows how Windows 12 will look like, and it’s stunning. This same concept creator has a long standing history of bringing his imaginations to life. He did something similar for the Windows XP 2022 edition and Windows 7 2022 edition.
Some of the main highlights of his creation include a refreshed Dynamic Taskbar and the new Start Menu. The new Taskbar is now dynamic and can give you important information at a glance." - Gizchina
Take a look at Addy Visuals linked in the quote, and the predictions re W10, etc.
