Controversy over next visa bulletin
There are two set of people who are posting information.
Few who didn't attended meeting with CO but got information on AILA site being a member of that group and few who are member of AILA and went to this meeting.
Those who didn't attended saying significant movement is possible from now to Feb 2012 but can't confirm March 2008 for Dec 2011 bulletin. While others like Murthy and few other law firms mentioned that it will be March 1 2008 as they might have heard directly from CO may be after meeting is over.
I would trust Murthy since if it is not even close to confirm she will not post on site home page.
Why CO will move to March 1 2008 ?
If he moves till March 2008 and USCIS start showing more and more demand from PWMB in Jan or later and he can't move date , still he is close to secure mode for this years quota for EB2 IC. If he can move in Jan - Feb 2012 , its a buffer for him.
Lesson learned from GC journey. When USCIS runs out of demand CO is very liberal and when they have enough cases CO is more conservative.
