Really? Is that why you can't find one anywhere? Sony actually sold all their cameras because PS4 streaming "just works" seamlessly, many people bought the camera and many more are eagerly waiting until they can get their hands on one. One could argue that the PS4 camera has more use then the Kinect ever did.
I actually really like the whole "Live on Playstation" It's cool to see so many people streaming on their ps4 and having their own shows and stuff. You can't even do that on xb1 that I'm aware of anyway.
