According to 9to5mac sources, Apple will come with major software changes in iOS 6 that is focused on improved interactivity when making purchases in iTunes, the App Store, and the iBookstore. “Social is a big piece of the store overhauls, and Facebook integration is being tested in the iTunes Store portion, at least“.
However, 9to5mac does not think that these new stores will include improved discoverability on the backend. “Apple recently acquired a company called Chomp that focuses on improved discoverability of applications. While Apple plans to use the Chomp technology across their three digital stores, the implementation will not be ready in time for the iOS 6 launch“.
