I have heard that the terminal at Cambridge WILL go ahead as planned. There are planty of other people in the wings who will fill that terminal.
Cambridge is a first class airport, great runway, nav aids and now a new radar, airport director and handling agent. It is just a matter of time until it gets busier, Marshalls have done OK over the last 100 years by taking things slowly.
Watch Cambridge, Stanstead is so busy (and expensive)maybe the next London airport?
Hey, what do I know, I only teach people to fly....
