Actually, Nemo, I don't think that is right at all. If you look at the
German, Spanish or French Wikipedia, for example, the German and Spanish
are totally stable, with no decline at all discernible around 2007, while
editor numbers for the French Wikipedia are actually growing:

I said "a turning point", i.e. a singularity; mainly, from positive to
non-positive derivative, whether negative or not. Of course, it's easier
to see in a graph than in a table.
I don't see French growing: except an outlier in November 2012 for
active editors, which is not reflected in the very active editors count,
in the last few months it's at the same level as in January-March 2008,
4800-5000 active editors.
It's the same in Italian, growth till January-March 2008 and then
oscillation/stagnation: http://stats.wikimedia.org/EN/TablesWikipediaIT.htm
Anecdotally in WMIT, we've been repeating "it.wiki has 500 very active
editors" for a while, and we've stopped updating this figure a long time
ago. :-)
Of course I'm only playing the stats dilettante here.
Summaries and charts for all projects are available here:

These three projects are of a similar age to the English Wikipedia, and
they are definitely not following the same editor retention pattern at all.
You're using the "editor retention" term quite incorrectly by the way:
those tables show only total active editors, old or new, not how many of
the new editors are still active, nor how many "really new" editor we had.

I think I've replied already. :-)
"New editors" is not reliable because one edit is enough, number of
edits or (new) articles have too much bot noise, database size/words is
often useful but even more often not available for WikiStats performance
limitations.
