Sony hasn't formally unveiled finalized pictures of the retail version of PlayStation VR just yet.
But it seems one reporter who has seen the device has an interesting piece of info pertaining to size.
According to Polygon , the first retail edition of PlayStation VR will require an external processing unit, and that unit is "a bit smaller than a Wii."
The device uses the external processor to ease the burden of rendering those fancy VR graphics, and the headset plugs directly into the unit. Then the whole thing is connected to PlayStation 4. The reporter in question was speaking from memory after seeing PlayStation VR on display at a recent games event, so there's no way of knowing what he means exactly by "a bit smaller." For the record, the Wii is 4.5cm wide, 16cm tall, and 22cm deep; the PS4 is about three times that size, by the way.
