The recent turmoil in satellite TV content contracts (Viacom-DirecTV example) seems like an indication this confab can shed light on directions going forward as Apple quitely and confidentially moves toward an internet data only video and content feed system akin to Apple TV and iTunes, but possibly integrating content feeds directly rather than through aggregators and broadcast networks (cable and satellite companies).
It is in content providers and Apple's interest to remove a layer of cost and "stickiness" and "friction" and directly provide content feeds and menuing systems. The problem for the content owners is Apple has a meme of standalone content. Buying or renting content by the episode, series, channel are definitely going to be separate options. Content providers are already choking on DirecTV objecting to both a 30% package price increase, but also being forced to take the whole package. There are some channels they are at loggerheads over.
However. There is still the issue of basic access. Some if not most locations simply don't have access to high speed internet via wire to the home. Those that do have fiber, copper, cable and probably others. Satellite downlink is fast enough but uplink sucks.
Then there is the <40% of the population stuck on dial up or 2G wireless or worse, nothing at all.
Netflix DVD might become less ubiquitous, but is will be a necessary utility for several years to come.
As for Cook's disposition, just like Steve, when he is in these meetings, he has already done years of research and planning and he is there with a monologue. The media reports of that are generally negative so having fewer of those make sense. Right until the product is announced.
Maybe he is on a Hillary Clinton-esque "listening tour." "It takes a village."

What the other guy in the meeting should do is listen. Intently.
