He assumes everyone who bought a PS3 will automatically buy or be interested in a PS4 and everyone who bought a 360 will buy or be interested in an xbox one.
These aren't different people (outside of the fanboys), these are the same people and the same market.
People aren't buying an xbox one, because people aren't interested in buying an xbox one.
Even if his statement made sense or held any truth (it doesn't), he would be implying that all of the games released for xbox one so far aren't good enough to get people interested in it or that Microsoft simply failed to make the console attractive enough for people to want one.
He's taking shots at his own product with statements like these.
He also says the reason they unbundled the Kinect was because people can't afford both the box and Kinect at the same time, not because people just want the box but no Kinect at all.
And today's news, Mehdi said, is also being driven by feedback.
"The decision we're announcing today is offering a choice to people that would allow people to buy an Xbox One and then ramp up to Kinect when they can afford to," he said.
Also he knows people don't want the Kinect and it hurts the sales of the console, but they still had mysterious motives to push it.
"We have been working with our developers and game publisher partners for awhile trying to balance two goals," he said. "One is the accessibility of the Kinect and the other is the desire for customers to onboard to Xbox One. They want both, a large audience of users and the best features.
Who exactly is they? Did he forget to mention a third or fourth group they've been working with that would benefit from the mere presence of Kinects, even if they are not used for gaming?
