AMD to start Bulldozer AM3+ production by March 2011, launch in April 2011

[informal]

Read carefully,I said probably.Another key word.
From Bobcat IP to launch was ~2 months or slightly less (IP Nov 2010,launch 2 months later at CES January 6). Zambezi is IP in April.If we take ~2 months as in Bobcat's case,we get to roughly the same time frame which is end of May or beginning of June(still Q2). Computex fits perfectly :

# COMPUTEX 2010 was held June 1 to June 5 2010.
# COMPUTEX 2009 was held June 2 to June 6 2009.
# COMPUTEX 2008 was held June 3 to June 7 2008 and expanded to TWTC Nangang Exhibition Hall.
# COMPUTEX 2007 was held June 5 to June 9 2007.
# COMPUTEX 2006 was held June 6 to June 10 2006.
# COMPUTEX 2005 was held May 31 to June 4 2005, adding a new feature "Buyer's Day".
# COMPUTEX 2004 was held June 1 to June 5 2004
