Microsoft crammed a lot of information into a one hour press conference.
To create the most advanced Xbox system ever designed for games, TV and entertainment, Microsoft created a state-of-the-art gaming operating system and fused it with an equally amazing entertainment platform, so you will not have to switch inputs to watch TV or play a game. An eight-core, x86 processor and more than 5 billion transistors helps make lag and load times a thing of the past, so you can instantly jump between a game and your entertainment at lightning speed or run a host of apps right alongside your game with no loss in performance.
