A number of people chiming in with the usual comments about "entitlement". And, yeah, they may have a point, this time.
But as I said in a different topic, look at it another way: Microsoft is effectively training people not to be early adopters. Does that really make good business sense?
It's pretty clear with things like pre-order incentives and the way big companies tout their sales figures that early sales are important. People want to buy the same console their friends are buying; people want to buy the consoles that are going to get the most attention from publishers. Publishers, in turn, want to put out games for the systems with the biggest install base; they don't want to put time and R&D into backing a horse that may peter out a few miles down the road.
I don't own a XB1 (or a PS4, for that matter, at least, not yet.) I don't have a direct stake in this. I just continue to find Microsoft's behavior a little baffling. Even as I understand that they're often being placed (or placing themselves) in "lesser of two evils" situations, I'm not at all sure they've made the right decision here, especially given how little game support the Kinect has received thus far. A showy, free Kinect-only title for early adopters would be a great way to show that they weren't forgotten, even if it was quickly assembled and short, more of a proof-of-concept than a commercial title.
I feel like I've been hearing a lot of discontent about the functionality of the Kinect, never mind its price. Going this way seems like Microsoft admitting the Kinect itself was a mistake.
