The statement comes from The Verge but I have no reason to doubt them.
I'm not sure why people are so bent out of shape about this connector. Having seen it in the Apple store, I'm very impressed with it ... Long overdue once you see it. The whole issue of digital driving up the cost of docks is also kind of silly, since the whole reason I buy a dock is to get direct digital quality. The analogue docks I have suck. By all means charge me a little more and give me a higher quality DAC in the dock than they affordably can cram in the iPhone, or an adapter.
I just hope somebody makes a 9-pin to 30-pin adapter so that I can forward-invest in the new docks, rather than continue to buy old docks, until I upgrade.
