In his rolling release proposal, Rick Spencer, Engineering Director at Canonical, has said that the new rolling model should be implemented now, with Ubuntu 13.04 Raring Ringtail, which meant Raring wouldn't be released.
According to a recent announcement, Ubuntu will use its own Display Server called Mir. The reason for this is that "none of the existing solutions would allow us to implement our vision without taking major compromises which would come at the cost of user experience and quality".
A while back, it was decided that Ubuntu 13.04 Raring Ringtail will ship with GNOME 3.6 for the most part instead of GNOME 3.8.
Raring Ringtail might become Rolling Release but if/until that happens, Raring users can add the GNOME 3 PPA, which was updated recently, to upgrade to the latest GNOME 3.8 beta for many components, including GNOME Shell and Nautilus.
This release focused on getting rid all all the bugs and make NeonView stable, and in 0.8.1 most of the known bugs should be gone. The core code has been rewritten and the application’s design is quite robust now, working the way it should.

The Ubuntu Touch Developer Preview has been released. This includes the source code and images for both the phone and tablet interfaces and are aimed at developers so it's not something you should install for actual every day usage.
