I'm not trying to be inflammatory with this question! I can't any statements though from Oracle regarding the future of Solaris, and wondered if there were any press releases or official notification of future versions. As I understand it, work has been greatly scaled back on Solaris and it's not being developed at a great rate. Is Solaris 11 the final party, with endless security updates to come but nothing else?

Solaris 11.2 includes over 500 new features including:
