MacOSXRumors claims to have additional information on Apple's upcoming Mac OS X 10.5 Leopard revision. According to their sources, they claim that Leopard will incorporate collaborative tools to allow users to work on documents over the internet: Support for such collaborative features are expected to be built into a framework for developers, and Apple is expected to integrate these features into future versions of iWork and iCal. A release target for Leopard is said to be January 2007. The reliability of this information is uncertain. Previous claims of integrated virtualization into Leopard have not yet been substantiated. Very little solid information about Apple's next version of Mac OS X has been revealed. What is known at this point is that Apple plans on demoing Leopard at WWDC 2006 in August. Apple has also publicly stated that Leopard will incorporate the final version of Boot Camp which is currently in Beta.
