It’s the leaked icons that suggest that something interesting is on the way.
Per MacNN, a series of icons that seem to be downloaded from Apple servers whenever someone enters the Storage Management panel, suggesting that Apple is laying the groundwork for the updated software. Visually the icons have been changed to adopt the flat, colorful design of iOS 7.
Apple has yet to issue iOS 7 overhauls for a number of first-party apps, including not just iPhoto and GarageBand, but other important titles like the iWork suite. The company has been racing to fix problems in iOS and update its entire ecosystem, however, and may be putting apps on the backburner. One possibility is that redesigned apps will make their debut at the October 22nd iPad event.
Stay tuned for additional details as they become available.
