If there was any intention to bring back the passengers they would not have auctioned off everything that was even bolted to the floor like check-in desks, security scanners etc. Why would they sell everything and then have to buy it all again at a price no doubt higher than what they got. It won't happen I am sorry to say.
The land is an asset but the airport is a liability. The company is known as a builder and not an airport operator so the writing was on the wall they day they got their hands on the airports land bank.
