If I got the PS4 I wouldn't buy the camera. Not including it wouldn't make the comparison fair.
Why?
Microsoft have made the choice to add the Kinect to the basic package, therefore you can't add a camera for the PS4 when comparing basic packages.
If anything it's a negative for the XBONE imo as I have to pay an extra £60 for something I don't want. I think Microsoft will lose some of the "on the fence", like myself, as the PS4 is cheaper and doesn't give you something you don't want.
I see what your saying but I have no problem with the kinect being included. It encourages developers to support it. Even taking the camera out of the equation. The PS4 with 2 games would cost around £430 the same as I've paid for the Xbox with kinect.
