Yes. Remember, I started with fancy talk about storms and climates, otherwise known as cyclical changes and structural changes. The collapse of the U.S. housing market is cyclical. Maybe they won't build mega-houses ever again. I don't know. So far, I don't see the shift in U.S. culture. But they will continue to live primarily in family dwellings, and they'll continue to build them using timber framing.
This means that you can pretty well predict the demand for lumber in North America if you look at population. As the population grows, more people grow up, have their own families and want a house. It's not happening now because the mortgage debacle in the U.S. that started this entire multiple double-dip near recession led to a huge overstock of housing in the U.S.
Until that is cleared up, people will not start building houses. But the demographic pent-up demand for houses exists. People are living with their parents. They're sleeping on their friends' couches. They've moved in with their uncle and aunt. As soon as they can get a job, and as soon as there is some return to economic growth, one of the first things they're going to want is a bit of privacy and their own house. The demand will then come back.
