iDownloadBlog claims that iTunes 11 will be rebuilt “from the ground up” with a new layout and iCloud integration. Apple hasn’t changed iTunes’ interface for ages, and the music application is long overdue for a makeover. It has become so slow and bloated that many users only cling to it to sync their iDevices. Apple may also integrate the iTunes Store directly into the rest of the program, instead of retaining the current in-app browser design.
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.
