Today at 10 AM PDT, Apple will be streaming a live keynote which is expected to introduce new or updated products and more information about the next iOS and OS.
The page suggests that you should ask Siri – “Hey Siri, give us a hint.” Try it and see the response. Also, the website states “See the announcement of Apple Music, get a preview of OS X El Capitan and iOS 9, and learn what’s next for Apple Watch and developers.”
You can watch the event live from Apple’s website.
Additional details will be made available from Apple as the event gets closer.
