Apple has confirmed that October 22 is indeed the day to look forward to as it has sent out official media invitations. The event will be held at the Yerba Buena Center for the Arts in San Francisco and will begin at 10:00 AM Pacific Time.
As we mentioned earlier, the event is expected to be primarily about an update to the iPad line which will likely feature a 64-bit processor (A7), Touch ID sensor, and updated camera. We will also likely be hearing more about OS X Mavericks and possibly the new Mac Pro. Many are also hoping for an updated mac mini, likely to be equipped with new Haswell processors.
