Microsoft is previewing their new MSDN Web site today, with the official rollout expected tomorrow. Apparently in response to Microsoft's "no Java" policy, the new design gives developers a one-stop location on the Web for tools, resources, and information. Particularly interesting for this week, of course, is its coverage of the Professional Developers Conference, which runs Tuesday to Friday in San Diego. Check out MSDN's "Live at the PDC" page for details.
