If you haven't checked out KDE I'd really reccomend giving it a go, as of 4.2 it's completely stable for me and has loads of cool features, 4.3 should be even better.
Back on topic, I'd forgotten about gnome-art but could do with some work and also it get's the icons/themes from gnome-art instead of gnome-look (which has better content IMO)
KDE rocks. Now that we are at Karmic Koala, it would be a perfect time to switch to KDE by default.
KDE 4.3 beta will be out in a few days, and KDE is now so far ahead of GNOME that it is ridiculous.
This would be the perfect "new look." Changing color schemes is not a "new look" .... changing to KDE... now that would be something!
I don't think KDE should go under the moniker "Kubuntu", I think the desktop Gnome version should be "Gnomebuntu" or "Gubuntu" (gnomebuntu sounds better) and then server edition and cli-only edition should be referred to as Ubuntu.
I wouldn't mind switching to KDE if the following apps had a GOOD Qt frontend: Firefox, GIMP, Pidgin. Until then, it's gtk/gnome for me.
I doubt that day will ever come, GNOME is going strong and the focus of the two platforms is towards different target audiences. I don't think KDE could be in a position to replace GNOME to the satisfaction of the existing Ubuntu community while also remaining true to what the KDE users love about KDE. Mostly in that several of the design goals are directly in conflict.
I say this as one of the biggest GNOME cheerleaders there is.
For now I am happy that the GNOME and KDE camps are working together on so many standards and that we today have a situation where the developers and users conference is held together. It feels much more like everyone is pulling in the same direction instead of trying to steal users from each other. I have been here since KDE1 and GNOME1, the improvement is vast, both in technology but also in community spirit.
On strike during the Oneiric cycle due to ungratefulness of Ubuntu.
