It is sad to hear about Goose Island (I am very sad that my home state is losing a VERY talented brewer as well).
My biggest fear for GI is seeing what happened when Pyramid came around and bought a large percent of some Pacific NW breweries. Quantity over Quality became the new mantra and after closing some and moving production of others outside Oregon and Washington, their local advertising as well as tap handle numbers have all but dissapeared.
With the craft beer market share continuing to increase, I think we'll see more and more of this, as the Big Breweries look to increase sales. Bud has their grips in the CBA and I can see Red Hook, Kona and Widmer falling into Bud's stable as well (RH-38%, Kona-35%, Widmer-40% of shares.)
