Isn't Sony the company that is mandating that every game features remote play for the PSV on PS4? Why is it OK for Sony to mandate companies include PSV cross/remote play for PS4 games, but it isn't OK for Microsoft to include Kinect in the box for a reasonable sum on day one?
Last I knew Microsoft wasn't mandating that gamer studios support Kinect, it's just there if they do decide to use it.
