IMO the big thing deals like this do for FBR is give real negotiation power / force buyers out. No major builder wants to loose market share because five years of sales of the HX sit between them getting a HX while their competitors already have one or several. A comment like "we are looking at locking in contracts for our first five years of HX production, and we've had global interest." will put huge pressure on other groups to sign MOUs.

If its 11 houses in Perth, people will treat it like a neish market, 50,000 homes in Saudi, you know that the tech is serious. Get 1000+ HX orders to help negotiate a good CAT binding agreement - CAT will put a far better deal on the table.
