Anyway, that whole "we aren't currently providing wayland support" quote has been taken horribly out of context. The context being, that's standard PR marketspeak, which says nothing. Companies say that all the time, and then the following day they can come out and say they are now providing support. The point of saying things like that is to provide wiggle room to allow them to do whatever they want. If they really were against Wayland, they would have come out and said they were never going to support it.
Let's just look at the facts.
Wayland is announced.
Nvidia says they aren't currently supporting it, but leaves open the possibility they might one day, if it ever gets important enough.
Mir is announced.
We learn NVidia has been working on an EGL driver for several months previously to the mir announcement. What exactly do you think that was going to support, if not wayland? There was nothing else on linux that required egl at the time.
Canonical states they are talking with nvidia to get them to support a common egl driver across both mir and wayland.
Nvidia officially says nothing, still leaving open the possibility that they could either do nothing and support neither, support both, or anything in between.
At this point, it's rather obvious that they're going to release an EGL driver, and that it will support both. Because it will be trivial to do so, once either one of them is supported there's basically already support for the other one completed.
The only real question is when that driver is going to be released, and the answer is going to be, whenever the first major distro is released that requires it. Whether that is Ubuntu or Fedora, we'll have to wait and see.
