Things have happened more slowly than this announced schedule.
However, I am currently working on removing E4X support with the
intention that the E4X implementation will be removed in Firefox 21,
which is due for release on 2013-05-14.
The patches are basically done and are in the reviewing and testing
stages now. If things go smoothly, the patches may land by the end of
this week. See

and

details.
