One of the questions we had about the PS4 before tonight was what kind of storage would it be packing. How big would it be? Is it built in? Would it be removable? Well, Sony answered it in their Japan press release for the PlayStation 4. It's a 500GB HDD, just like the Xbox One.
If you want the PlayStation 4 Eye, it'll run you up 60 bucks. Same cost as a PS4 controller. Getting an Eye for the PS4 would still make it cheaper than the straight shot $500 for an Xbox One + Kinect but of course the Kinect is much more powerful. [Sony Japan via Engadget]
