Apple is set to announce new iPad models on 22 October. We may even get a release date for Mavericks then, and maybe some more info (dates, pricing) of the new MacPro.
The fifth-generation iPad is expected to feature a thinner, lighter design akin to the iPad mini’s, and an improved camera. It will run Apple’s new 64-bit A7 chip. The second-generation iPad mini will be upgraded with a retina display and also likely see the A7 incorporated into its innards. It’s not clear whether Apple’s new iPads will feature the Touch ID fingerprint sensor that recently debuted on the iPhone 5s, though that has been rumoured.
Location isn’t yet confirmed, but may be the Apple Auditorium in Cupertino or the Yerba Buena Arts Centre in San Francisco.
