Oh, now I get it. Yeesh, sorry, I misunderstood. People are talking about the App Store on the actual iPads themselves, not the iPad App Store in iTunes.
Sorry, carry on.
Edit: I'd read about this update this morning, and I've been checking iTunes at random intervals ever since, trying to see the iPad section. It didn't even dawn on me that the update was talking about the App Store on the actual iPad.
