Is there a target date for release of the production SL 6.

I have a need to rebuild a number of servers from other Linux OS's and would 
like to have a guess as to when we may expect SL 6.   I remember that the 
guess a while back was March 11.

I am putting together a plan for 2011 as to what new equipment we plan to 
purchase, the OS used for the new boxes, minnor details I need to put in my 
yearly plan.

Thank You
