x11 is in maintenance mode at this point and Gnome is not going anywhere. Gnome is used (and financed) by major distributions.
Nothing new is being created with x11 and the people from freedesktop don't seen to be thrilled to maintain it. I don't think should change just for the sake of changing, but I'd start looking to migrate whatever you use that depends on x11.
