iPad 2 Case comes with a Camera hole and 1 Mysterious Hole

Looks like some Chinese manufacturers know how to form and shape of the latest generation rumored iPad will be present in April next year. Some chassis manufacturers have made a special casing for iPad 2 is either in the form softcase and hardcase.

From the pictures you see, there are holes in the back of the camera, a dock connector (not two as has been rumored), and a mysterious hole in the bottom right. Not yet known to what function these holes, the possibility of an SD card slot is also small because the hole is large enough to the rear of the chassis.

Another speculation is intended to predict the antenna hole (unlikely) or for new speaker design may be located similar to the old iPad speakers. Will iPad 2nd generation has an appropriate design, such as the casing that has produced long before its release this? Just wait for its development.
