It's gonna be short, just in case somebody is interested.

In 20 minutes (5:30 CET) there is MS conference held at Electronic Entertainment Expo. Tomorrow Sony and Nintendo will have their time.

Update: Sony Press Conference is about to start in 15 minutes. You can find the video stream somewhere at GameSpot
