Sea change in progess?

The Wall Street Journal has this bit today (you've got to be a subscriber to read the whole thing, but the main news is in the free nugget): Anheuser-Busch will begin allowing some of its distributors to carry competing brands.

How big a deal is this? Aren't AB's exclusive distribution deals one of the major tools it's used to build it's mammoth market share? Is this a sign that we should expect to see even more craft beer on store shelves around the country?

I can't lay hands on a copy of the whole WSJ to read the whole thing. Any body out there seen it?
