In ten years they won't exist as we know them. There'll be a small core of die-hards living in secluded compounds and several splinter groups that go more mainstream. The die-hards will still put out literature, only not from the printing facilities in Brooklyn which will either be sold or seized. The Watchtower and Awake? of that time will be cheap flyers that are a mix of those wacky tracts that Fundies hand out, wild conspiracy theories, and the same few scriptures they've been wearing out for the last 100 years.
They also won't be going door-to-door in 10 years so the "do more" part will be only about money.
Mike.
