Apple's biggest event of the year is happening next week - here's everything it's expected to announce

Apple traditionally releases a new Apple Watch alongside its fresh iPhones in September, so there's a chance it could do so again this year.

The next-generation Apple Watch, which could be called the Apple Watch Series 5, may come in new finishes, according to Bloomberg. These new options could include titanium and ceramic, as a leak hidden in the watchOS 6 beta discovered by iHelp BR indicates.

Apple is also expected to introduce sleep tracking to the Apple Watch, a feature that competitors like Fitbit have long offered, reports Bloomberg.

Apple took the wraps off its long-rumored move into subscription-based entertainment services in March.

But it has yet to announce crucial details about Apple TV Plus and Apple Arcade, such as how much these services will cost, when they will be released, or what the selection of content will be like at launch.

We're expecting to get at least some of those answers during Apple's fall event, especially considering the company has been releasing trailers for upcoming shows that will be part of Apple TV Plus.

Apple will also probably announce when the new software updates for its product lineup will be available, as it has done during its September event in years past.

Apple unveiled new software for the iPhone, iPad, Mac, Apple Watch, and Apple TV during its Worldwide Developers Conference in June, as it usually does during the event. The updates typically roll out to the general public in the fall, usually in the September timeframe, so there's a strong chance we'll learn more about the availability of these updates next week.

Apple is rumored to be working on several other new gadgets, although it's unclear if we'll see them next week since the company usually focuses its September keynote on iPhone and Apple Watch announcements.

The company is expected to launch a new MacBook Pro with a 16-inch screen, a new iPad Pro, and a new entry-level iPad before the year is over, according to Bloomberg. It also hasn't announced when the $6,000 Mac Pro it unveiled in June will be released. However, Apple typically waits until October to debut new Mac and iPad products, so we may not see these new products just yet.

Apple may also be working on a Tile-like Bluetooth accessory that you can place on items like your keys or wallet to track them via your iPhone, according to 9to5Mac.

Apple has emphasized the importance of privacy in recent years, especially as companies like Facebook and Google have come under fire for the way they collect and handle consumer data.

Apple CEO Tim Cook has publicly said on numerous occasions that privacy is a fundamental human right, and that the consumer is not the product for Apple since its business doesn't heavily rely on advertising as Google and Facebook products do. It's even centered its product ads around privacy in recent months.

There's a chance Apple executives will mention privacy and security again during its expected iPhone unveil next week.
