I don't want to guess on this topic. If Mr. Deucher, Airlie and the likes will post about how they think Wayland is really needed than I think it's important. Until then I'll follow the drastic improvements in the Xorg stack even without Wayland.
I agree with the man that all the problems of the Linux desktop are being fixed right now, except Xorg which is developing too slow (I didn't say Mesa). It will be intersting to see what Google will unleash with their Chrome OS, because rumours are they've done a new Xserver or something in that regard.
