OS X 10.9 to feature Siri, use Apple's new Maps APIs
OS X 10.9, the next major iteration of Apple's operating system, will apparently include Siri, the "intelligent assistant" that first appeared on the iPhone 4S in late 2011. In addition, Apple's new mapping back-end will replace Google data for Core Location APIs, according to sources speaking to 9to5Mac.
Anticipated to arrive sometime in 2013, references to OS X 10.9 have been popping up in server logs for several Apple-related websites recently. 9to5Mac's sources explain that the development of OS X 10.9 began at the same time as OS X 10.8, with various new features assigned to each release. Such a strategy makes it possible for Apple to move to a yearly update cycle for its desktop OS.
