Previous reports had suggested that Apple would take the wraps off its new iPads and announce the release date of OS X Mavericks a week before on October 15th.
It is unclear why the date has changed. It is unlikely that Apple would have moved the event because of HTC and Nike announcing plans to launch new products on the same date.
Indeed, the new date of October 22nd is the date that Nokia is expected to announce its first tablet, and the date the Surface 2 hits retailers.
Reports have pointed to a new full-sized iPad, a iPad Mini with Retina display and new Macs – including more details about the Mac Pro – to be announced at the event.

The new full-sized iPad and iPad Mini with Retina are rumoured to be getting the Touch ID biometric security system found in the iPhone 5s.
It is also expected that OS X Mavericks will see its release date announced. The next version of Apple’s desktop operating system was shown off at WWDC in June, but the company refused to put a date on its release.
Reports suggested that it was pushed back to ensure that iOS 7 was finished on time for the launch of the iPhone 5s and iPhone 5c last month.
