And as I said before, what are the developers going to do? Not develop for the console?
Yeah, I don't get the problem with doing so. It didn't kill the 360 to not have a Kinect in every bundle. I get that they want to push the tech, and that's why I even suggested a compromise of not offering the option for 6 months to a year. What it boils down to is Microsoft is forcing all Xbox One owners to purchase a Kinect without proving its value and quality beforehand. If this was the third-generation Kinect, and the second was a high-quality product, it would be different.
Instead, the first-gen Kinect had loads of input lag and ignored commands until the fifth time you said them (assuming you didn't just get frustrated and close the disc tray yourself). There were neat features of the Kinect, and it has loads of potential, but I really dislike the idea that they are expecting everyone to pay an extra $100 for the console on what amounts to users' hopes that it will be 5 times better (because that's probably the low-end of what the improvement needs to be to make the games responsive). Even the demo that I saw showed noticeable lag, and that means that fast-paced games like shooters (which could be argued to be the console's main selling point) might not work well with the Kinect just yet (maybe tweaks and such since that demo will prove to make it more responsive).
I don't know that it REALLY matters to me, though I know it will to many. I've accepted having to buy the Kinect, but it also means I will be waiting until next year to do so (probably would have happened either way, but I would have been more-likely to get it this year if it was $400). It also means that I will have time to read reviews about the Kinect (as I'm 99% sure I am the first person I know who will take the plunge on it, so I cannot test it out first-hand before purchase, most likely). If it turns out that the second-gen Kinect is lag-prone again, it's going to cause problems. No one will like it if using the Kinect slows down your gameplay and gets you killed in shooters (though non-shooter fans won't care about it). However, it will mean waiting for a significant price drop or a non-Kinect option before I buy it, because I simply cannot justify the waste of $100 for a piece of tech that won't do its job when I want it to (as I don't do Netflix of any of that, I'd want it only for its gaming purposes).
