KDE plans to tackle that through two already ongoing projects: Ocean and Union. Ocean is the new design system, while Union is intended to provide a unified theming engine across applications, Plasma, window decorations, and Plasma Login Manager.
I don’t think they are the same category of thing. Ocean is a design system. Breeze is a theme.
Edit: now I’m less sure. This seemed to say it is both a style and a “design system” which I took to mean a technical mechanism for styles, but now i’m less clear what they mean.
It’s clearly stated in the article.
I read it. It does not say if Ocean will be the successor to Breeze.

Oxygen is still in KDE, so I doubt Breeze is going anywhere.
Thank Ahura Mazda for that. I love Oxygen so much!
