Microsoft has been quiet about its plans for the Xbox 360's successor, but it's certainly doing something behind closed doors. Microsoft has beefed up security tremendously.
Microsoft employees were notified recently that access to many of the buildings on its Redmond, Washington campus would be limited in order to maintain secrecy. Apparently, this sort of security is typical of companies like Apple, but Microsoft is usually more open. Something is happening behind closed doors in Redmond, and we can't wait to find out more. New consoles are always exciting.
