In his newsletter today, Gurman said watchOS 10 will be a "major" update with "bigger enhancements," including an "updated interface." He did not provide any additional details, so exact new features and changes remain to be seen.
Gurman said minimal hardware changes are planned for the next Apple Watch models, so watchOS 10 will apparently be a major focus this year.
The first watchOS 10 beta should be made available to Apple Developer Program members very shortly after the WWDC keynote, while the first public beta will likely be released in July for those enrolled in Apple's free Beta Software Program.
