I'm not certain that is, statistically, the case.

The trouble is that there needs to be a sufficient plurality in favor
of *a particular move onwards* in order for it to happen.
Right now, what we see is:
- Some that are fine with status quo
- Some that are keen on Subversion
- Others keen on Monotone
- Others considering other options; Darcs, Git, Mercurial, Arch...
There's no majority there, for sure. No plurality, either.
There has been a "convulsion" of activity surrounding SCM in the last
couple of years, and I think that the brief trouble that the Linux
kernel had with Bitkeeper going away has been an *excellent* thing as
it drew developers to work on the (long languishing) SCM problem.
It looks as though there is a strong "plurality" of PostgreSQL
developers that are waiting for some alternative to become dominant.
I suspect THAT will never happen.
I think instead, that we will see three or maybe four of the newer
SCMs being jointly dominant.
- Subversion has a clear body of happy-enough users for Subversion to
- Git, being the Linux kernel SCM, will continue unless some
heretofore undiscovered fatal flaw bites it.
- Mercurial seems to have enough user projects to be viable.
(OpenSolaris, ALSA, Xen, ZFS for Linux are probably recognizable
It seems plausible that one of [Arch, Darcs, Monotone] would also
This contradicts the notion of there being any single dominant
successor to CVS; if that were the case, that would make a migration
I think, instead, that we'll continue to see a multiplicity of
choices, meaning that the best we can do is to eventually pick one.
There isn't enough of a 'plurality' of support for any one SCM to
allow that to take place now.
