Microsoft issued the following statement:

On Tuesday May 21st, we'll mark the beginning of a new generation of games, TV and entertainment. On that day, we'll be holding a special press event on the Xbox campus and we invite you to join us via the live global stream that will be available on Xbox.com, Xbox LIVE and broadcast on Spike TV if you are in the US or Canada.

On that day, 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.
