I agree that the Reinheitsgebot would most likely be followed for most beers even after its potential annulment, just because there is too much cultural stigma against "unpure" beer. But still, there is more change in German beers than most Germans like to realize. Kölsch for instance, the beverage that defines much of the culture of major parts of the Rhineland region, has only really become popular in the middle of the twentieth century -- despite all the alleged traditions ascribed to it.
