I've just finished the main work for deltah. The only major things left are BurningDog (Karl is working on this), and waiting for the FSF to give us more disk space so Hardy/deltah can fit on our build and archive boxes.
Assuming we've got those before Hardy is released, I'll drop support for deltad and spin a 1.9 LiveCD as a release candidate.
The following things are not done to the level they could be: 1 Usplash
2 Gdm login screen 3 Gnome background 4 Gnome icon themes
For 3 I can hack daleduro's artwork into place, but the rest aren't so easy. If someone can produce gNS versions of human-icon-theme, ubuntu-wallpapers, usplash-theme-ubuntu and ubuntu-gdm-themes in the form of a debian source package (i.e. tarball) I can add them in. Please focus on ubuntu-gdm-themes first, as daleduro has already produced some artwork for this that we can't get in easily otherwise.
I've done nothing for KDE, and it looks like there will be no supported upgrade path from deltad.
