NPD's numbers on digital don't tend to have much reflection on reality. As much as I would love digital distribution to take over the world, I can't think of a single publisher (including ourselves) that sells even close to a majority of its units digitally. I am a big believer in the future of digital distribution but the numbers we typically hear from publishers is that it's about a third (which is pretty darn good, by the way)
