Microsoft: Xbox 360 not even met in his life
This especially in light of the upcoming "rebirth" of the console through the motion sensor Natal Project, expected by the end of the year along with a healthy line-up of games dedicated. Furthermore, the issue of further software upgrades will make the console always fresh and in line with the needs of users.
Microsoft seems therefore very optimistic about the future of their console, but we believe this does not mean they will spend another 5 years before we see a new console as has happened with PS2 and PS3, it is possible that early (between 2012 and many think 2013) leaves a new Xbox, while the "old" Xbox 360 will continue to remain on the market for several years, representing a low-end option for players who want to spend less demanding and less.
