Apple's "Gather round" event at the Steve Jobs Theater at Apple Park begins at 10:00 a.m. Pacific Time, where it is widely expected to unveil three new iPhones (XS, XS Max, and XR) as well as new, slightly larger Apple Watch models.
We should also be hearing final details and the official release date for iOS 12, and likely macOS Mojave, watchOS 5, and tvOS 12 as well. And, of course, there may be other announcements and surprises in the cards.
Apple itself leaked a number of details this morning by prematurely updating its store site maps, and we have a summary of what's been revealed right here.
Apple is providing a live video stream on its website, via the Apple Events app on Apple TV, and on Twitter. We've shared instructions on how to watch along with a list of when the keynote starts in time zones around the world.
In addition to Apple's video stream, we will be updating this article with live blog coverage—no need to refresh—and issuing Twitter updates through our @MacRumorsLive account as the keynote unfolds.
Highlights from the event and separate news stories regarding today's announcements will go out through our @MacRumors account.
Apple's online store is currently down in advance of the event. It should be accessible again shortly after the keynote.
