Fedora 18 was not released on schedule, but knowing how the Fedora project operates, this was no surprise, because unlike other distributions, a new Fedora edition is almost never released until all major issues have been fixed.
What makes this delay unique is the stable release will not hit public download mirrors until next year. And I think this marks the first time that a Fedora edition has been pushed back this far. But now that a beta edition has been released, here are some screen shots from test installations of the KDE and GNOME 3 editions. (You might want to read Install Cinnamon on Fedora 18.)
First screen shots are from the GNOME 3 edition.
I call this the blue wall or blue curtain. I think the Fedora project should be shipping a GNOME 3 edition with a custom GNOME Shell, rather than the default GNOME Shell
