Rich raised one facet of interest.
Would you go the way of Ubuntu, and work around Gnome mainly? Or the way SuSE traditionally was, and be mostly KDE oriented?
Here's my 4 possible path outlines.
#1 Find a way to make the Distro desktop agnostic at core. With a painless selector at install or some earlier stage.
#2 Status Quo. Distro comes the way it's creator decides. Has it's points.
#3 Go to extremes. One release is "Heavy" with all possible "Eye/Ear candy, Second is skeletal between single fd to BBC size.
#4 Variant of #1 -Desktop of choice installed by online setup from repository.
