Apple is hosting an event in New York City on October 30th. The event will take place at the Brooklyn Academy of Music, Howard Gilman Opera House, and it'll kick off at 10:00 am EDT/7:00 am PDT.
As for what Apple has in store, the company's invitation says "There's more in the making" with a stylized Apple logo. We've heard rumors that Apple is working on a new iPad Pro model, and so it seems likely that the updated tablet could debut at this event. It's rumored that this new iPad Pro will have slim bezels and will ditch the Home button, option instead for a Face ID unlock system like on the iPhone XS and iPhone XS Max.
Refreshed Mac hardware is also rumored for this event, including an updated MacBook laptop and possible a new Mac mini as well.
