There were whispers going around earlier this month that Apple has already begun to test out early builds of Mac OS X 10.9, where it does seem as though Cupertino is pretty adamant on delivering iOS features onto the OS X platform. So far, it seems that early builds do point towards the integration of Siri and Maps, although we do wonder why would anyone want to use Apple Maps on their desktop when you can always fire up a browser and rely on the far more accurate Google Maps.
At this point in time, Apple does offer both Dictation and Text-to-Speech, but when you take into consideration Siri integration, chances are Mac users will then be able to take advantage of voice-command as well as search functionality to boot. Maps integration, on the other hand, would mean developers can incorporate it into their own Mac apps, and it remains to be seen whether Apple will put up on offer its own stand-alone mapping app for the Mac. We await with bated breath for the official release of Mac OS X 10.9, and will keep a keen eye out for it on the grapevine as well as official news channels.
