Well now there is Mir, Wayland, and X, instead of just X. Just right there you now have three codebases instead of one, so that is fragmentation in itself. Is it harmful fragmentation? I think that remains to be seen.
I'm not worried about fragmentation though.
My position is that currently X "Just Works" for me and I am not willing to sacrifice this stability so that I can test out the pet projects of a bunch of Red Hat and Canonical employees. I figure I have at least 3 years, hopefully 5, before I will be forced to switch. (3 years left on wheezy, and hopefully 2 more years with jessie assuming X is still the default and viable). 3-5 years to let them work out all of the kinks? Yes please, I'll take that.
A lot of the Wayland developers are X developers. It basically is X12, just that calling it X results in a lot of unneeded steps (loads of people will have a say into the spec, etc). Daniel Stone explained this in a video.

The dust sure as hell better be settled by 2018.
