(via Laurent). Based on their requirements, the Mozilla.org team is moving to Hg (Mercurial).
OpenSolaris, OpenJDK and soon GlassFish are moving to Hg as well as you probably already know.

Mozilla betting on Hg
Will NetBeans? :)
I don’t know, should they?
At any rate, a NetBeans mercurial plugin is in the works.
For me, it’s just a source of constant amazement that such big and complex projects as NetBeans, use CVS, with all its limitations and quirks and bugs, not to mention its centralized nature.
I think it does make sense to move to better source control systems, and distributed SCM as Mercurial is probably the right way to go, esp. since OpenJDK and OpenSolars and Glassfish are already switching.
As for Netbeans Mercurial plugin, that would be super!
What advantage has Hg over subversion??
svn is (just) a (much) better CVS.
Mercurial is distributed.
Vladimir, the Wikipedia page which compares various SCM systems has a nice table that may be useful in tracking down the list of differences between Hg and SVN:
http://en.wikipedia.org/wiki/Comparison_of_revision_control_software
Other comparison pages can be found too, of course; I just pointed at this one (even though some of the Wikipedia information may slightly out of date), because I like the tabular comparison sheet.
