The next major release of X.Org was scheduled to be released February 2008 - and then May 2008 - and now it's missing, with no sign of when a release will occur. There's still more than three dozen outstanding bugs. This forthcoming release (X.Org 7.4) will also ship with a slimmer set of features than what was initially planned.
On top of that, X.Org 7.4 is shipping with a slimmer set of features than what was planned. X.Org 7.4 was supposed to have Multi-Pointer X (MPX), but that was delayed (though it will be ready for X.Org 7.5). Also sliced out of this release was input hotness, or XKB 2 and Xi 2.
It appears more people are worried about the degrading quality of X.org releases. Out-of-date documentation, blocker bugs lists that are not empty, the complete tree and module set not buildable on one platform, and despite the 200 day delay, X.org 7.4 still has blocker bugs. For such an important piece of software, this is not an ideal situation.
