Nice piece by Mike Shatzkin this:

Well, I said, that would be true, but the problem is you’re going to face a lot more competition. Demand may go up and costs may go down but if supply in competition with publishers’ outputs rises too fast, there could still be a very difficult period in front of the industry’s legacy players.

That is: it could get increasingly difficult to get consumers to give you money.
