We may also see a new Apple TV set-top box, and if we're lucky, hear what's on deck for the coming quarter, which Apple chief executive Tim Cook previously made clear on its fiscal second quarter earnings call in April.
For those who want to follow along with the event, Apple will be streaming the announcement live from Apple TV devices, and from its website.
From the main screen of the Apple TV, users can scroll down to find the "Apple Events" slide.
For web users, users must watch the stream online with Safari on iPhones and iPads running iOS 4.2 or later, Safari 4 or later on OS X 10.6 or later, or on an Apple TV (second, third generation) set-top box with software 5.0.2 installed or later.
The event begins at 10am PT (1pm ET; 6pm BST).
But, if you're at work or away from the screens, you can keep up to date with breaking news from ZDNet throughout the day, or by following @ZDNet on Twitter. You can also keep track of events live from sister site's CNET live blog on the ground.
