iTunes 11 leaks surface with first clues
New rumors mixed with more concrete details has pointed to Apple actively testing iTunes 11. Test build screenshots slipped to 9to5 purportedly have a central iCloud panel that would control all iTunes-related iCloud features, such as iTunes Match or device backups. The build would also have iOS 6 compatibility, although it might not be necessary and could be preceded by a 10.x update instead.
Apple's iTunes Store revamp was also supposedly being timed for a launch in the second half of the year. The company's acquisition of Chomp had led to a specific iTunes content discovery task force, according to the rumor.
The app as shown looked familiar, although Apple may be developing different components independently and integrating them at a later point.
iTunes 10 has been one of Apple's longest-serving versions of its jukebox app. It was first unveiled in September 2010 and, while getting interim feature upgrades, has been mostly the same underneath. A major version number would point to more substantial upgrades, whether it involves iCloud or a new interface.
