Hopefully the brewpub scene here will go the way of people looking for unique beers, rather than just fresh beer, which is their big marketing point. Their only outpost in Portland, OR (one beer mecca) is, um, not encouraging.
Edit: That said, the whole brewpub thing in the States has gotten big enough that many, if not most, major hotels, conference centers and such are expected by the public to have a brewpub onsite. Many of these are extract based, and this system fits that perfectly, and probably makes better beer. So I guess I should say that hopefully the brewpub scene here will get big enough that this system finds its niche, but most places brew from scratch.
