It's as simple as a single stroke of divine wisdom. You get rid of the numbers. Next is wrong - new is what everyone cares about. If you're telling people they're getting the ultimate, the last thing you want them to think about is what comes later. Numbers are about the order of appearance, the new iPad is about the order of succession. In the royal sense, all three iPads look almost exactly the same but, to be fair to the new iPad, it brings a massive upgrade.
The 2048 x 1536 pixel Retina display has four times the resolution of the previous model. The bar is yet again set too high for the competition. And it's a leap worth several generations. Apple did well to make sure the monstrous screen is well covered in terms of graphic processing with some extra GPU cores too and the performance is flawless, The 5MP camera is an improved version of the one on the iPhone 4 and the video recording is duly upgraded to 1080p.
