Microsoft will reveal the next-generation Xbox, and successor to the Xbox 360, in an online presentation on May 22 at 3am, AEST.
The event will be live streamed on Xbox.com.au and through Xbox Live.
"We'll share our vision for Xbox, and give you a real taste of the future. Then, 19 days later at the Electronic Entertainment Expo (E3) in Los Angeles, we'll continue the conversation and showcase our full lineup of blockbuster games," said Xbox's Larry Hryb.
Microsoft's next Xbox could feature glasses-free 3D, room-wide television projections, tablet functionality and could even require a constant internet connection if rumours are to be believed.
