An as yet unconfirmed rumor has outlined minor but significant details of Apple's 2012 roadmap. The tip to iLounge had the iPad 3's dual LED backlight leading to a rare increase in an Apple's device thickness, by 0.7mm (0.03in). The thickness would still keep it thinner than the original iPad but would show a sacrifice to get the rumored 2048x1536 display, whose density would reduce the amount of outbound light without the extra LED.
