The PlayStation 4 might be $399, but how about the devices used to control it? Both the DualShock 4 and the PlayStation Eye are not going to be huge bank busters if you are worried about that.
Sony has confirmed that both the DualShock 4 controller and PlayStation Eye will be priced at $59 each. Of course, the console will come with one DualShock 4 controller, so no more are necessary to purchase.
The PlayStation 4 will not come with a PlayStation Eye camera though. Luckily, the device isn’t as engrained into the console as the Kinect is for the Xbox One. you have the option to buy it and enjoy it for all it’s worth, but ignoring it is just as easy an option.
