I seriously don't see that happening with Unity. The community justly or unjustly voiced their dismay with the project, I vote unjustly. I don't see where Unity fits in with a world of KDE, Gnome and hundreds of other DEs.

Unity was made to unify people's experience with using it on a tablet, phone or desktop. It is pretty clear that the only thing left is desktop. I don't see what is unique that would compel a developer to continue another project when they create their own or join one of the bigger projects with an already established community.

Personally I love KDE and i3. I never use anything else for years because I don't have a problem I am hoping to solve through another project. What does Unity offer for a person to switch?

If you like to customize and have lots of options = KDE

If you like things to have less options and "just works" = Gnome

If you lie _____ and ____ = Unity
