A prototype of Apple’s new HomePod is displayed during the 2017 Apple Worldwide Developer Conference (WWDC) at the San Jose Convention Center on June 5, 2017 in San Jose, California.

I don’t think we’ll see Apple’s new Mac Pro, which it said it will launch this year, but Apple likes to surprise its audience. I’m also curious if Apple decides to talk more about HomePod, its smart home speaker that will compete with Amazon’s Echo. That’s supposed to launch by the holidays, but Apple hasn’t really provided a whole lot of information on what the user experience will be like. We’ll also learn about the price and release dates of the iPhones and new Apple Watch.

CNBC reached out to Apple for comment but a spokesperson was not immediately available.
