Debian Jesse is going to have Gnome3 as the default desktop.
The desktop re-qualification page, used to help choose which desktop will be default, has in the Jesse version a weight for systemd integration, and of course only Gnome3 does it (at least for now). This will surely make the systemd/gnome3 fanbase happy, but possibly will make others unhappy, as it [may] be seen as another step towards mono-culture, until we soon end up with all distros being redhat clones.

I thought they dropped Gnome3 as default simply because they had not yet switched to systemd, and Gnome3 requires it. Now that they've adopted systemd, it was possible to return to Gnome3 as the default. i.e., they would have preferred to keep Gnome3 as the default, but could not for a while because of the systemd dependency. With that dependency satisfied, they were then able to return to Gnome3.
Now why they would make Gnome3 the default instead of KDE, I have no idea. Sit a Windows (XP/Vista/7) user in front of both and see which one they're immediately productive with. It won't be Gnome.
