Those major home builders will probably be lining up to place orders as soon as pilot production begins -- so they can claim the environmental / product-safety high-ground. NEXBOARD could easily make Drywall obsolete overnight. Why would anyone want to use a 100-year-old technology when there'e a better, safer, eco-friendly alternative available for about the same price? (Don't forget, NexBoard is made of plastic and cardboard waste products -- stuff that probably doesn't cost them a cent!)
