Eight years after the first Xbox 360 units shipped, Microsoft will finally pull the curtains off its long-awaited successor, thought to be the Xbox 720, on 21 May.
The company is holding a press event at 10 a.m. Pacific Time (6pm UK time) that day that will be live-streamed on the Web.
"On that day, we'll share our vision for Xbox, and give you a real taste of the future," Microsoft said on the website.
The company plans to talk about the console games a few weeks later at the Electronic Entertainment Expo - widely known as E3 - which will be held in Los Angeles June 11-13.
The Microsoft announcement follows Sony's announcement of the PlayStation 4 in February. The PS4 gaming console hasn't been shown yet, but is expected to become available later this year during the holiday shopping season.
