With Apple's WWDC behind us and the first iOS 27 developer beta out, you'd think that we now know about all of the major features that are coming to Apple's mobile platform when it properly launches this fall.

However, there still may be several pretty major, yet-to-be officially announced features that are on the way.

According to Bloomberg's Mark Gurman, one of these is a simplified Modular Ultra watch face for Apple Watch. The Modular Ultra is a high-tech, snazzy watch face that's exclusive to the Apple Watch Ultra, so getting even some sort of simplified version on the other Apple Watch variants would be pretty cool. Apparently, the simplified variant will have one fewer row of customizable complications than the version on Apple Watch Ultra.

Another feature that Apple hasn't announced at WWDC, despite rumors that it's coming, is a customizable Camera app. As is, the Camera app does come with a new Siri mode, but Gurman previously said Apple would include the option to customize the interface with widgets.

Finally, Apple was rumored to add third-party chatbots to Siri, but only ChatGPT made the grade in the iOS 27 developer beta. Gurman claims that other models, including Gemini and Claude, might still make an appearance come fall.

We've checked the latest developer betas for iOS 27 and watchOS 27, and none of these features are available right now. Gurman isn't sure why Apple decided to leave them out, but he's pretty confident that the company will include them once the new iPhones and Apple Watch devices launch, likely in September.
