Google I/O, the company's annual developer's conference, doesn't start until May 20, but expectations are already swirling about what will be announced during the event. Here's what we think might show up at this year's Google I/O, plus details on how to watch.When and how to watch Google I/O 2025This year's Google I/O is scheduled for May 20 and 21, with the first keynote beginning at 10 a.m. PT (1 p.m. ET). The event will be live streamed online at io.google and on YouTube. Anyone can view the keynotes and sessions without registering, though developers can register for free to receive event communications. What's coming to Google I/O 2025The schedule for I/O 2025 hasn't been published, and what we think we'll see is (so far) based on rumors, speculation, and leaks. That said, there are a few things we can reasonably expector at least hope for. First is the launch of Android 16, which Google has already pegged to Q2 2025. According to Android Police, leaks suggest an official release date of June 3, meaning an announcement at I/O is likely. Public betas have been rolled out with new features for photography, security, device management, foldable detection, and small tweaks to accessibility and health functionality. Another possible release date announcement could come for Wear OS 5.1, which has some relatively minor new features and stability improvements. And while Google isn't expected to launch Wear OS 6which would follow suit with the release of Wear OS 4 in July 2023 and Wear OS 5 in July 2024or even announce any of its features, it could hint at what we'll see in Wear OS in the future. Finally, Google recently confirmed the launch date for the first Android XR-powered headset and revealed more details about specs and features. This came following Samsung's extended reality (XR) prototype reveal during January's Galaxy Unpacked event. Other hardware news is less likely, as the Pixel 9a is expected to drop in March ahead of I/O. Of course, AI is expected to be heavily featured at I/O 2025, with possible updates about Project Astra. The "advanced seeing and talking responsive agent," announced at I/O 2024, is billed as a next-gen AI assistant that can receive real-world inputs and respond to what it sees. The event lineup could also include updates on Gemini features like Circle to Search, AI Overviews, and integrations with Android, Search, and YouTubeand maybe even the official switch from "Hey Google" to "Hey Gemini."
