I will try to attend Oracle OpenWorld 2011, it will my first time and I think this year will have a lot of information regarding the SPARC T4 and Solaris 11. It has been almost a year since we saw the last bits of the Solaris 11 development so I expect there have been substantial changes. Maybe the Solaris 10 Update 10 release will be kept unannounced until the conference, it's already been several weeks since the KUP was released on MOS.
Expect regular updates if i manage to attend the event.
