FYI, System Center Operations Manager 2012 RC is now public
Also now is a GREAT time to sign up for Microsoft Management Summit (MMS 2012) if you haven't already:
With our entire System Center 2012 suite due to release the first quarter of CY12, and MMS taking place in April, MMS is going to be HUGE this year.
