I'm looking forward to using the ps4 eye. I think, if they were to learn from the Xbox 360 mistakes with kinects. They will apply the usage in a more creative manner and produce games that can actually benefit from the ps eye.
It's not on my radar at the moment, but if there is an opportunity to purchase it at a great sale price, I might, just to have it in the event a game comes along that appeals to me and utilizes the accessory.
Is there any more actual footage of the camera being used in a game? Hell, now that i come to think of it, is there any footage of the Kinect being used practically in a game without it being a pain in the ass.
But honestly, i think i would get the camera just for the facial recognition login alone.
I want to know more about it really. What the resolution is, the uses, what games it will work with and why, if it works with the move, whatever. I think social gamers may buy it at launch. I currently do not even know anyone with a ps3 let alone anyone who can get a ps4 (myself included) so the social part for me would be worthless.
