I'll try to answer the first two at least.
You're asking about what the new building products are. In response to an earlier question I mentioned that we already have a wide range of products that can be used. The next step for innovation, to me, is how to put these products together to form a building system. You can probably do it in the factory, which is now becoming more popular, because it saves construction time and so on. We shouldn't be looking so much at the products; we should be looking farther downstream in terms of the solution for builders to be able to put together a building more cheaply.
You're right about wood being an attractive feature. This is why architects around the world like wood, apart from the fact that sustainable building design has now become a real issue. I think we need solutions that are functional and will make wood's appearance appealing to the consumers.
