Every year, Apple holds a big press event at its conference for developers and tells the world about its future plans for the iPhone, iPad, and Mac.

Now, there's a new addition to that lineup: the Apple Watch.

Apple doesn't usually talk about its plans or future products until it's ready to unveil them to the world. But the company wants us to know that big improvements for the Apple Watch are coming.

"Third-party apps will get much better," Jeff Williams, Apple's senior vice president of operations, said at a conference last month.

This is one of many announcements Apple is expected to make on Monday that will tell us about the company's direction for the year.

Here's a rundown of what else we might see:

Apple's answer to Spotify

This is among the biggest announcements we are expecting to see.

For months, reports have suggested Apple will debut its own streaming-music service that sounds a lot like Spotify. It will probably cost $10 per month, according to The Wall Street Journal, and Apple has been said to be in talks with various artists and record labels to beef up the music selection. The service, which is said to be called Apple Music according to Bloomberg, will be powered by Beats Music, which Apple acquired last year. There will also be an Android version of the app, which is a first for the company.

It's an important move for Apple if it wants to reestablish the dominance it asserted over the music industry when it introduced the iTunes Music Store in 2003. Now streaming is becoming more prominent than downloads, and Apple needs to catch up.

Analysts don't expect the music service to add too much to Apple's revenue though — hardware is Apple's biggest moneymaker. If Apple's streaming service attracted as many subscribers as Spotify (15 million), it would only add less than 1% to revenue in 2016, assuming Apple charges a $10 monthly subscription fee to each subscriber, the analysts at Piper Jaffray report.

The next big update for iPhones and iPads

Apple will also show us the new features we'll see on iPhones and iPads with its next software update, iOS 9. It probably won't be a big aesthetic change like the last update, iOS 8. Instead, Apple is said to be focusing on stability and security. In particular, Apple is reportedly making an effort to ensure older iPhones and iPads will be able to run the software smoothly, unlike previous versions of the software that usually ran slowly on gadgets from years past.

Apple is said to be making big improvements to Siri, too. The new Siri will look more like the version that appears on the Apple Watch, and it'll be able to communicate with other Apple apps such as Passbook, Calendar, and Spotlight search, as 9to5Mac's Mark Gurman writes. It sounds like a much-needed answer to Google Now.
