This tournament was supposed to be in Bangalore last year, but was canceled a month before it was to take place due to security reasons (there were some bombings there last July). Previously, the tournament was moved to Bangalore from Mumbai in May 2008 (just a few months after it was moved 2 weeks later on the calendar due to the monsoon season). The tournament was in Mumbai in 2006 and 2007, and prior to that in Ho Chi Minh City.
When the 2009 calendar was first released, this tournament was listed to be in Bangalore. I don't know why it was changed and where it will go.
