name='Ars Technica' said:Microsoft's original plans for Windows Media Player (WMP) 11–formerly code-named Aurora–were fairly low-key, with just a few minor new features. That's all changed: Microsoft has canceled Aurora, and the company is moving the Longhorn media player to XP. Now code-named Polaris, WMP 11 will be a major release. There's just one problem: Instead of shipping in November, as per the original plan, WMP 11 will now ship in a public beta during that month, coinciding with Longhorn Beta 2. The final release is roughly scheduled for early 2006. You heard it here first.
