premise: 
  Anheuser-Busch Cos. said it plans to aggressively discount its major beer brands, setting the stage for a potentially bruising price war as the maturing industry's growth continues to slow.
  Anheuser, the world's largest brewer and U.S. market leader, has historically been reluctant to engage in price-cutting as a means of boosting sales volume. With the passing of the heady days of swelling industry sales, however, the once-sporadic and brief forays into discounting are becoming standard competitive weapons in the beer industry.
  Over the summer, Anheuser competitors offered more and deeper discounts than industry observers have seen for a long time. Some experts now predict Anheuser's entry into the fray means near-term earnings trouble for all the industry players.
   What might happen if Anheuser-Busch aggressively discount its beer brands?
