The Ubuntu community has been asking this question ever since the Meizu, Bq, and Canonical partnership was announced. The developers didn't want to provide a clear answer to the launch question and only the launch window was provided, the fall of 2014.
The Ubuntu developers are working to promote an RTM (release to manufacturing) version of Ubuntu Touch and they are almost ready, but it looks like they still have a couple of months, at least, to polish it up. The operating system still needs a few more features, but above all it needs stability.
After writing earlier this week about a new AMD Catalyst driver paving the way for X Server 1.16 in Ubuntu 14.10, the updated packages have officially landed within the Ubuntu 14.10 "Utopic Unicorn" archive.
The updated AMD Catalyst driver has xorg-server 1.16 ABI compatibility, which for weeks was blocking X.Org Server from being updated in Ubuntu to avoid forcing users to run the open-source AMD driver, etc. Now that AMD sent over this updated driver that has yet to be publicly launched on AMD.com, Canonical went ahead and pushed down the X.Org Server 1.16 update and the updated DDX input/video drivers with compatibility for the new server. Those packages are now in the official Ubuntu 14.10 "Utopic" package archive for anyone doing daily testing of the distribution.
Still packages and found within the Ubuntu Utopic (14.10) archive are the various Wayland packages. Right now within Ubuntu Universe is Wayland 1.5, the Weston 1.5 compositor release, and various other Wayland-related packages like for VA-API acceleration, the basic GLMark2 benchmark for Wayland, etc. Granted, most of these packages were just supplied by the upstream Debian base and are of no special interest to Canonical. The Wayland packages for Utopic can be found by this package search.
While Ubuntu 14.10 is finally getting X.Org Server 1.16, it doesn't yet have Mesa 10.3 but that can be easily addressed via third-party packages.
Mesa 10.3 will hopefully still make it into Ubuntu 14.10 ahead of its debut next month since Mesa 10.3 brings many new features to the commonly used open-source Intel, Radeon, and Nouveau graphics drivers (along with promising drivers like Freedreno and VC4). If you want to try running the newest open-source user-space graphics driver code on Ubuntu 14.10, it can be easily achieved today using the well known Oibaf PPA.
Two months after the release of X.Org Server 1.16, AMD finally has readied a Catalyst Linux driver update that is compatible with the latest xorg-server ABI. This driver is being sent into the Ubuntu 14.10 archive and thus allowing the entire Linux graphics stack in Ubuntu 14.10 to finally be updated.
Sent into utopic-proposed on Tuesday was a new fglrx driver version. The new fglrx driver is labeled 14.201-0ubuntu1 as a new upstream Catalyst/fglrx release. While there is no full change-log for this driver, the Ubuntu change-log notes that the driver is compatible with xorg-video-abi-18 as the Application Binary Interface requirements for X.Org Server 1.16.
I read an interesting article on OMG! Ubuntu! about whether Canonical will enter the wearables business, now the smartwatch industry is hotting up.
On one hand (pun intended), it makes sense. Ubuntu is all about convergence; a core platform from top to bottom that adjusts and expands across different form factors, with a core developer platform, and a focus on content.
