I feel like there has been a welcome proliferation of styles, at least in my area. There are multiple breweries concentrating on lager styles and multiple breweries concentrating on sours. (Everybody has their styles that they don't get the popularity of, and for me, it's sours. I like a few from time to time, but it mystifies me to see shelves and shelves of them, and I rarely feel like trying a new one.) My favorite development in recent years is that there are a variety of dry stouts available to me, instead of just Guinness.
Regardless, sorry to tell you, but IPA has long since passed its initial fad stage. New styles of IPA can take over the IPA niche in an annoying way once in a while, but IPAs as a category have reached a stable level of popularity that seems to be sustained as new generations of beer drinkers enter the scene.
