Pending EB2 485 applications after April 2010

[gpkreddy7]

Hi All, Why the USCIS has not released number of pending EB2 485 applications after April 2010? Is the USCIS hiding it intentionally. Do any one has estimate on how many pending application will be there in the years 2011, 2012 and 2013 for EB2?

Thanks for the help.
