So the big news here is the screen resolution, which is bonkers. At 2048 x 1536 pixels, it has significantly more pixels than not just the old iPad, but also your 1080p HDTV and just about any other "HD" screen you've got lying around. Apple's again referring to it as a "Retina Display," which means that you won't be able to see pixels with your bare, weakened, organic eyeballs, at least from the 15-inch distance Apple estimates most people have between their eyes and their iPads. (Note: Apple is clearly excluding cats, which have more sensitive eyes and sit closer to the iPad anyway. This is offensive, probably.) That'll mean every publisher is going to have to re-do their apps for the new resolution, the same way they had to for the transition from the iPhone 3GS to the iPhone 4.
