Yast "New Installer"
The Yast team started development of "new Yast installer". It actually won't be a complete rewrite of the Yast installer, it will be rather a refreshing, refactoring and adding some enterprise features (for SLE12 - SUSE Linux Enterprise 12). But of course, these enhancements will be also present in the next openSUSE release (openSUSE-13.2, 13.1 is almost done).
We just started public discussion about it, if you have some ideas about the Yast installer just join the discussion at yast-devel mailing list.
See the announcement, more details will be published later, stay tuned...
