True or not, you don't expect them to confirm the console everyone wants right before the launch of the console they want everyone to buy do you?
Oh of course not. But I don't see them giving in on Kinect ever. A price drop in a year (or less), if its selling poorly? Sure. And same for Sony if the PS4 sales were lagging. Time will tell on that.
But I imagine Kinect will always be packed in as I imagine some core games will require use of it and they're aren't going to want to render those games unplayable to future owners who buy a later bundle that doesn't include Kinect.
Plus it's just part of their core vision of the console. They want people to use and love gestures, voice commands etc. for games, interacting with their TV etc. They're going to sink or swim with that focus. Sink with me as I'll never buy one with Kinect included as I have no interest in it,and don't want to support it financially as I want motion/voice controls to die off (or at least stay for the casual/fitness/dance type games).
