According to the site, its sources say that early builds of OS X 10.9 integrate Apple’s Siri voice command software much like Apple’s newest iPad models running iOS 6.

Apple is expected to make its mapping software available to developers keen to offer mapping features built in, while Siri implantation expands on the addition of dictation in 10.8 Mountain Lion.

It's a trend that has already been used in Apple's mobile operating system iOS with the iPad 2 getting dictation a release before getting full Siri support some time later after Apple was able to iron out any issues.  

OS X Mountain Lion was released in July after being previewed to developers and Pocket-lint in February. That suggests we could be learning about the new features of OS X 10.9 in just a couple of months.
