I wonder what this means for their mobile devices.
I seem to remember them saying that the desktop users needed functionality in Mir that the mobile didn't, so the mobile would be available sooner. I desktop/mobile convergence won't be ready until after Mir is ready for the desktop.
Personally, I'm not certain how viable Kubuntu on X/Wayland will be in the long run, but that's at least as true about Kubuntu on Mir.
We'll get to the long run, in the long run, but for right now Mir/XMir offers us nothing but complication.

Given that the major concern I've seen expressed is that the Kubuntu team won't have resources to maintain their own display stack ...
Compositing may be fragile, but there should be no difference visible to KWin between XMir and native X with respect to compositing.
And given the tendency for bugs to arise as a result of mismatches between X+mesa, or X+mesa+kernel, I would be much more worried about native X not receiving the attention it needs to be kept in sync with mesa - a problem that won't arise with XMir, since Mir+mesa are obviously going to be maintained as a usable combination.
So I'm not convinced that XMir actually represents complication for Kubuntu, rather than beneficial alignment.

We are about to release our benchmark results as part of the public Ubuntu QA dashboard. We will inform the community once the data is available.

The difference between Unity + X and Unity + XMir + Mir may not be so different, I can't say the same for Lubuntu.
So things actually go even faster than expected for Mir. It's gonna be funny to see what the Wayland fanbois have to say about this. Mir started later and finished faster than their beloved project. And you will still say that Canonical can't write code for shit and that they never created anything.
This is excellent news.
I've always been a desktop and mobile convergent device that'll run essentially the same OS with a unified display server.
Ubuntu for Android looked interesting, but what they're pioneering with Ubuntu Touch will be fascinating to watch.
It's also sad to hear that Kubuntu will be switching to Wayland, but I suppose that's their choice. They never really offered anything besides an boring vanilla KDE experience in the first place.
