We are not too sure of whether or not the above pictures are the read deal.. but if they are they definitely suggest that the tablet will feature a design scheme very similar to that of its mini version.
We can see that there may be dual speakers adjacent to the lighting port as well as separated buttons for volume control as opposed to the usual volume rocker from its predecessors. The sides also look a bit more tapered which is another design feature that is seen on the iPad mini. If this pictures are in fact real, we may be able to expect a much more refined design on the iPad 5.
It may also be worth speculating that the next iPad may feature different color options as well. This comes into question seeing as both the iPhone and iTouch have color choices which only leaves the iPad left behind.
