IIRC, Joyent's stuff is built on Illumos, which is an open-source fork of Solaris 10 created when Oracle announced Solaris 11 would be closed source. The Illumos developers put in considerable work ensuring Illumos would be feature-compatible with Solaris 11, but it's not like they were adding new bits of Oracle code or anything. Illumos will continue on their own just like they've been doing for the last few years. They'll probably have even more freedom to innovate even, since they won't have to worry about chasing Solaris 12 compatibility. Edit: And Joyent is one of the major sponsors of Illumos, too, so their platform definitely isn't going away.
