Serial Attached SCSI - 2 (SAS-2) revision 8 (sas2r09) is now available
on and, 
incorporating proposals recommended by the March 2007 T10 plenary
(e.g., the new TLR control mechanism, removing address resolved method 
of zoning, and adding the expander "reduced functionality" mode).
The goal is to start T10 letter ballot after the July 2007 meeting
week; the 6 Gbps physical layer specifications will probably be the
gating item.  Please:
* review the editor's notes that have accumulated
* review pending proposals and send comments to their authors. 
  The current WG agendas are at:
  - and 
* prepare proposals for any other changes you want
Letter ballot resolution usually takes 2 meeting cycles (allowing
the final draft to age for 2 months).  So, if letter ballot really
happens in September, forwarding to public review would probably
occur in January 2008.
There are no plans for a SAS-2.1, so changes made after SAS-2 is
published would have to go into SAS-3 working drafts.  SAS-3 will
probably remain open longer than SAS-1.1 or SAS-2.
SAS-1.0: 5/2002 to 7/2003 (1 year, 2 months)
SAS-1.1: 7/2003 to 9/2005 (2 years, 2 months)
SAS-2:	 9/2005 to 1/2008 (2 years, 4 months)
SAS-3:	 1/2008 to 1/2011 (3 years)(estimate)
