Don't expect the shows to be announced early. No reason to announce them early, as things may change, and they will sell out in a few days anyway. The shows in South East Asia were announced just a few weeks before they were actually supposed to be on. See IORR news 2003 about Singapore, Bangkok, India and China.
Jan-27-2003: Asia rumoured shows in IORR news
Feb-16-2003: Hong Kong shows confirmed
Feb-20-2003: Singapore shows confirmed
This was just 4-6 weeks before the actual show dates in March 2003.
