iPod touch Will the new iPod Touch have a flat back?

Or is it going to be slightly curved again like the 4th gen? Flat back like iPhone 4/4s/5

As far as I can tell, the back is flat but there is a slight ring-shaped protrusion around the camera lens.

From everything I saw, it's flat. Why the camera lens protrudes from the case I don't get. They should have just made it a little thicker so it would sit flush, seems like the lines would be cleaner.
