iTunes current version is a total mess as far as programming is concerned as new major features are being introduced in the past are simply entangled in same program without a major software redesign.
We know Apple cares about these concerns so they are planning to redesign the software from scratch. All the major components like purchases, ipod music, applications, personnel contents, ibook and iPad sync are all prohibitive tasks.
According to a sourse taking to iDownload Blog, it has been confirmed that Apple will launch iTunes 11 in September this year which will be completely revamped and will provide better iCloud integration.
From what we’re hearing, the UI would be much more cleaner and “slick.” iCloud is also going to be more closely integrated with iTunes. Rather than the iTunes Store being essentially a web browser, the Store will actually be integrated into the entire app— much like Spotify is currently.
We’re also hearing that iCloud backups will be integrated into iTunes. This means if you back up your iDevice to iCloud, that same backup will be stored locally on your computer. Also, app data from iCloud will be synced closely with iTunes. For example, if you beat a level in Angry Birds, that level data will be synced to iCloud and then to your iTunes library.
It might be linked with launch of next generation iPhone and iOS 5 launched but nothing is sure at this point of time and we are keeping our finger crossed.
