As WWDC 2006 approaches, rumors continue to appear about what we could see at the developer's conference. MacOSXRumors claims to have reliable information about Mac OS X 10.5 (Leopard) which will be demoed at the expo. Previous rumors from the rumor site claimed collaborative features, and virtualization support. This time, the site claims that Leopard will incorporate virtual desktops, improved file syncing, and improved spotlight performance. Meanwhile, an unconfirmed Page 2 report claims that the Intel Xeon (Woodcrest) will find its way into Apple's new Xserve and top-of-the-line mac pro. Meanwhile, the lower-end Mac Pros will use the recently released Core 2 Duo (Conroe) chips. Other hints include a Merom update to the current line and new Leopard features, including some 3d effects. WWDC kicks off on August 7th, 2006 with Steve Jobs providing the Keynote address.
