The event is scheduled for 22 October at 6pm UK time (it's 10am Pacific Time). It will be held at the Yerba Buena Center for the Arts in San Francisco. You can follow the event live here on Macworld.co.uk. (See How to watch Apple's 22 October iPad event)
As ever, Apple followers will pore over the invitation itself for clues about what will be announced, and Macworld's very own Ashleigh Allsopp is casting her expert eye over it as I type. But the most obvious components are a large white Apple logo, with 'leaves' peeling off in an autumnal drift that's reminiscent of the iOS 7 Photos icon.
The tag line is 'We still have a lot to cover'.
Following the iPhone 5c and iPhone 5s launch last month, it was widely tipped that Apple would refresh more of its product lines, with most analysts expecting new iPads; Mac OS X Mavericks and the new Mac Pro may also get a mention.
It's believed that the iPad 5 could get a thinner, lighter design, and numerous leaked images back this up. It also seems likely that we may see a 'Space Gray' version, and a gold version isn't out of the question.
As for the iPad mini 2, there's not much floating around the web that gives us a solid idea of what we can expect, but we think Apple will eventually want to add a Retina display; whether that will come with the October update remains to be seen.
It's possible that both iPads will have the iPhone 5s's Touch ID fingerprint sensor technology, too.
