Everyone knows prop planes are drawn to mountains like tornadoes to trailer parks.
Why would they remove the kinect? They want to make sure devs know it is a universal resource so they program for it.
Because a lot of us do not want Kinect, or go further and hate or fear Kinect. First, because Kinect games are widely regarded as having poorer control systems than controller-based games, and second paranoia over webcams/microphones watching you in your living room. (I'm in the former camp).
How many have you seen that have say taped over the Facetime camera on their Mac Books?
The iMac in the cubicle next to me is that way. Admittedly it's the only one nearby like that.
Yes, the tape solution has occurred to me...I've so far avoided buying a computer with a built-in webcam, but that's the solution I'd use. I fully expect there to be DIY microphone disconnection demos online within a week of the console releasing (who knows what functionality it would gimp, though).
How awesome would it be if there was a line-in instead of an actual microphone? You could hook it up to something that would play pre-recorded taunts over Live (like that great robot-voiced "I am the alpha and the omega" from Unreal Tournament). Actually...maybe that would be a bad idea...
The universe is an island, surrounded by whatever it is that surrounds universes.
