WinRumors posted a news story that Microsoft is planning to announce the release of Internet Explorer 9 on March 14

Microsoft’s Internet Explorer 9 team is planning to host a party during the South by southwest (SXSW) music and film festival in Austin, Texas. The party will be held on March 14 and will include free drinks and music performances from Yeasayer, The Head and The Heart, and Fences. Microsoft has sent several invites for a “special press pre-event” to press and analysts over the past few weeks. Microsoft’s Australian PR company, Howorth, recently sent invites claiming Microsoft is planning a “major announcement.”

Sources familiar with the company’s plans have confirmed to WinRumors that Microsoft intends to launch the final version of Internet Explorer 9 at SXSW on March 14. A number of Internet Explorer 9 team members will participate in the launch and celebration party afterwards. The confirmation of March 14 follows news that Microsoft is currently compiling near final escrow-RTM builds of Internet Explorer 9. The escrow builds mark the final stage of Internet Explorer 9′s development. Microsoft’s latest Internet Explorer 9 escrow build is 9.0.8112.16416. Microsoft historically RTM’s products less than a month after they hit the RTM-escrow stage.
