Here's the original official product shot from Nyko, before the Power Grip was actually released. A few changes were made between the time this image appeared on the Nyko website and when the accessory was available for purchase. The main difference is that the Power Grip was originally planned to have grips that folded back out of the way under the body of the PS Vita. I suspect this feature was removed to simplify the device, and because it wouldn't really reduce the bulk all that much. You can read more about what I think of this change in my review of the Power Grip.
Read on to see the updated official product shot, followed by my own photos of the device, showing all the details.
