The companies that are betting on ZFS -- Delphix, Nexenta and Joyent (and a bunch more that are less public about their work) -- are overwhelmingly (indeed, exclusively, to the best of my knowledge) on illumos and FreeBSD. Of these, Delphix in particular is of note because of the original ZFS core team members working there: Matt Ahrens (the co-inventor of ZFS), Eric Schrock and George Wilson -- not to mention important ZFS contributors like Adam Leventhal and Chris Siden.[1]
So illumos remains the repository of record for ZFS -- with a close relationship with those working on ZFS on FreeBSD. While the Linux port is certainly a Good Thing, it does not reflect shift in the epicenter of ZFS development...
