I don't know if they're really concerned about boosting their main brand with the craft brands. InBev produced a Budweiser Super Bowl commercial slamming craft beer, particularly a "pumpkin peach" beer, just a week after they bought a craft brewer that makes a pumpkin peach beer. That leads me to believe that their goal is just to have separate brands that target different demographics.
