I'm sure it is just as they say in the article:

*** "During this phased approach, travelers will have access to a limited variety of retail and dining options, with several others set to launch in late November and December, all carefully selected to enrich the airport experience for travelers."

In the future, when all is complete including the Arrivals Hall, I am sure they will have a Formal Opening, of the redone terminal, with festivities and maybe visiting dignitaries, ie; maybe even the King & Queen would visit.
