The emacs development team is hard at work on emacs 24. As far as I know, there is no planned date for it yet. I'll write more about all the new cool things when we're a bit closer to the release date, but I'd like to highlight emacs 24 color-theming already, as it's an area people outside the core development theme should be able to contribute to as well.

by hand. If you design some attractive color theme and would like to propose
it for inclusion in emacs 24, you can send it to emacs-devel.
