iOS 7: Fingerprint, biometric technology?
Following Apple's $356 million purchase of fingerprint and biometric security firm AuthenTec last July, we can expect a number of security-related features embedded in the next-generation software. But what it points to, if the analysts and pundits are correct, could be a fingerprint sensor in the next iterations of the iPhone and iPad.
It could also open up the possibility that Apple may bring out near-field communications (NFC) technology to its phones to open up its devices to wireless mobile payments.
iOS 7: No more skeuomorphism!
One of the key changes expected in the next-generation mobile platform is the removal of skeuomorphism — a design that emulates the real item. The Notes app looked like a notepad, the Contacts app looked like a leather-bound organizer, and the Game Center sported a felt-like interface.
Instead, all apps will likely look and perform the same. New user interface guidelines may also be introduced as part of iOS 7 to bring a more consistent approach to the platform's design.
OS X 10.9 to be announced after iOS 7
We also know that OS X 10.9 will also be announced during the conference, but iOS 7 will likely have to be announced first, so the company doesn't blow the lid on any additions to OS X.
Apple has in recent years increasingly 'iOS-ified' its desktop platform with mobile-related features, in a bid to expand the wider ecosystem of Apple products.
