At the liquor store I work at their new black crown was flying of the shelves for a couple weeks and is already slowing down drastically. With most of the bud (non craft-like) drinkers they just want a light, clean, easy, & cheap beer to get drunk off.
Many off their craft like beers are good but their is no major hurry for bud to overhual their thinking as they (inbev) have a ~70% share of the beer market in the U.S.
