Do not want!
Even before the DRM stuff was announced, I had decided against the XBone based on this alone. That certainly doesn't change now. Even though I had a 360 this gen and didn't get a PS3, I'd much rather have a PS4 than an XBone due to this.
I don't like Kinect's features, I don't have a convenient way to hook it up in my entertainment center, I don't like some of the scary stuff I've heard about related patents from MS (like facial recognition ad targeting), and I don't want to be forced to pay $100 more for a console that is weaker because they feel their silly attempt to tap into Wii's market is somehow relevant now.
More than any of that though, I don't want devs to feel pressured to put Kinect functionality in all their games like Wii developers felt they had to replace button presses with wii-mote waggle. Having it a required component is going to do just that. PS4's camera thingy isn't built-in, so devs may add value-added features but if you don't care to use it, the vast majority of games on PS4 won't expect you to.
