Another reason to believe that the release of OS X Mavericks is just around the corner: Apple has started asking third-party developers to submit apps optimized for the new OS in the Mac App Store.
Apple wants devs to make sure their apps take advantage of the “great new features in OS X Mavericks when the world’s most advanced desktop operating system becomes available to millions of customers later this fall.” Such features include Timer Coalescing and App Nap.
The October 22nd media event is when Apple will likely announce the release date of Mavericks. Major updates to OS X are typically released a day after an Apple earnings call, and there just so happens to be one on October 28th.
