Like it's already been said, Move is for all functional purposes, built into the DS4.
Yes, I bought a Move controller and yes, I owned a PSEye as early as 2007; it was a good control option for the FPS games that incorporated it and I was very fond of Sports Champions, that may not have been as cute or accessible as Wii Sports (which I played as heavily as any normal Wii owner), but it did work more as advertised compared to the Wii Remote.
It's clearly not top priority for SCE, which is probably a wise decision given the luke warm response to Move, and more importantly, XB1 Kinect, which should really be one of the major selling points of the platform given that consumers are paying $100 extra for it.
We'll see. I'm willing to bet SCE and third party developers will release software that makes the PS4 Camera a bit more compelling, as much as I'm willing to lay down money to buy one in the future. There just isn't anything compelling currently, or announced for me personally.
