Doesn't look like there has been any update at all, which I find a real disappointment. I simply can't believe anyone actually uses the rear facing camera on the iPad, and I would have expected Apple to focus on improving the front facing camera to further improve the Facetime experience.
EDIT: the poster below makes an excellent point re the quality of the front-facing camera and the impact of that very poor device on an even higher resolution screen.
On the tech specs posted on apples site looks like it is still the super crappy VGA camera. wonder how crappy it looks on the new super dooper display.
