Canonical and the developers need to rapidly alter the theme for the next Xubuntu release. Since XFCE is so similar to GNOME 2.x, I would recommend basing Xubuntu 12.04 off the "classic" Ubuntu we see in 11.04 while in "Ubuntu Classic" and releases earlier.
As we all know, many people do not want to change to Unity, and find it very buggy. XFCE on Xubuntu offers the stability and feel of GNOME 2.x and the "classic" Ubuntu, which most people who know Ubuntu know best. Also, Xubuntu is currently, well... crappy! There are only basic utilities and themes, and there is pretty much no support by the community whatsoever. Xubuntu 12.04 needs to be the rebirth of the Xubuntu OS, bringing the classic features and looks we all know and love, while bringing the quality of Ubuntu to another playground.
