In the early hours of Saturday (Beijing Time), Microsoft and Nvidia almost simultaneously began teasing a mysterious new product set to debut next week via social media posts.
Pavan Davuluri, Microsoft’s Executive Vice President of the Windows and Surface hardware division, shared a photo appearing to show the edge of a curved screen. He captioned it, "New for developers is coming," expressing anticipation for meeting everyone at next week’s Build conference.
For context, Microsoft will hold its annual Build developer conference in San Francisco from June 2 to 3. While capital markets are primarily focused on the software giant’s progress in self-developed AI—especially following the redefinition of its partnership with OpenAI—it now appears that the hardware division also has noteworthy developments in store.
Davuluri specifically clarified that the upcoming product "is not a new operating system," effectively ruling out a Windows 12 launch next week.

Micron remains one of the hottest names in tech. JPMorgan noted in a recent research report that retail buying of memory chip stocks is "persistent and elevated," with no signs of profit-taking.
