Microsoft's Don Mattrick has described the new Xbox One as an "unrivalled device" in an interview with the BBC after the launch of the next-generation console.
The US firm described the voice- and gesture-controlled machine as an "all-in-one" system offering games, live TV, movies and music.
It will go on sale later this year.
