At the time of this writing we have no official word on what the "special addition" to Microsoft's E3 2009 Media Briefing is, we've been informed that the event will begin promptly at 10:25am PT, five minutes earlier than was originally scheduled.
Obviously, whatever Microsoft has decided to add to the show, it'll plan on covering in a short time. Could it be a teaser trailer for a newly announced title (or one that was leaked this past week)? Or maybe a new partnership to help strengthen their position in the industry? Only time will tell and we will be there bright and early Monday morning to bring you the latest news from this week's E3 show in Los Angeles.
PlanetXbox360.com will be bringing you the breaking news as it hits direct from the press conferences tomorrow and the show-floor later this week. Stay glued to our front-page features/news, forums, and make sure to follow our twitter (@PlanetXbox360) account for the quickest way to get instant 2009 E3 Expo related information.
