Sorry, I did not save links to the official Ubuntu discussions on the
topic. Please try not to read too much in the press releases, they are
horribly short on useful information. I am, however, paraphrasing from

This makes no sense whatsoever. The choice of default desktop has no
effect on any other desktops... XFCE, KDE, LXDE, all are still firmly in
place, and you are free to install as any as you want to use whichever
you want. Besides, Canonical is acutally going to use Compiz as the new
window manager, not Mutter.

The performance of the new compositing desktops will be more dependent
on your graphic card (which you have not specified).. your cpu and
especially, that large chunk of memory are more than sufficient for
current and future generations of Ubuntu. However, if your graphic
chipset/drivers can not handle a OpenGL desktop (more on that below,)
then you will have to use a previous generation desktop. In the next
version of Ubiquity (being created now for Natty,) Ubuntu is going to
use the Compiz window manager, which is able to degrade features based
on what the chipset supports. Finally if the chipset simply can't handle
the graphic engine, the desktop falls back to the classic gnome we all
know and love. I'm presuming this will also be an option to choose
(same as we are now able to turn off desktop effects, even though they
are enabled by default.)

Gnome is not out. Ubiquity is a shell that runs over gnome to make it
easier to use. Ubuntu has clearly stated that will continue to provide
gnome-shell packages and a PPA for the latest builds. It simply will
not be the default desktop on install. (And having tested gnome-shell,
all I can say is, thank god for that. What a disaster.)
