While we are still a week away from Apple unveiling iOS 27, Bloomberg's Mark Gurman has just shared the first rumor regarding iOS 28.

In his Power On newsletter today, he said that iOS 28 will be "far more significant" than iOS 27.

"Next year's '28' releases are already shaping up to be far more significant than the '27' updates," wrote Gurman.

iOS 28 is codenamed "Bell," while macOS 28 is "Poppy," he said.

iOS 28 would be the first version available on Apple's redesigned 20th-anniversary iPhone, which is expected to be released in September next year.

iOS 27 will seemingly be focused on a revamped Siri and additional Apple Intelligence features. The update will include the long-awaited personalized version of Siri, complete with on-screen awareness and better understanding of your personal context. For example, at WWDC 2024, Apple showed a user asking Siri about their mother's flight and lunch reservation based on info retrieved from the Mail and Messages apps.

A dedicated Siri app will allow you to have back-and-forth conversations with Siri in text or voice modes, similar to other chatbot apps like ChatGPT. In addition, iOS 27 is expected to add a "Search or Ask" feature to the Dynamic Island.

Beyond that, iOS 27 has been likened to Mac OS X Snow Leopard, in that sense that the update will apparently be especially focused on bug fixes and stability improvements. If so, it would not be too surprising if iOS 28 is more significant.
