That part is curious. Presumably the 3rd gen iPad is hardware capable, and I can't imagine there is a lot of software difference between the iPad's camera app and the iPhone's. The only thing I can think of is that they didn't have enough time to test it on the iPad, and that it'll come in 6.1 or so when they're sure it works perfectly. That's probably what happened with Siri for iPad.
