Ubuntu official repos do have GTK+3 (3.0.8 ) at the moment.
However GTK 3.1.2 was released last month and GTK 3.1.4 two days ago: http://mail.gnome.org/archives/gnome-announce-list/2011-May/msg00011.html
The new GTK 3.2 will be released on September 2011.
oh nice, thats a good news for our look & feel; this will really change usability
Right, the odd number releases (like 3.1, 3.3 etc.) are development releases so that's why they are not in Natty, but GTK+ 3.2 & Gnome 3.2 will be in Oneiric. By the way at this time, I don't believe we plan to ship the 3.1.* versions in the Natty Gnome 3 PPA, just the 3.0.* updates.
In fact, that's why Ubuntu releases when they do, just long enough after Gnome's 6-month release cycle to finish polishing things up and ship.
Cheers for the heads up harry.
