I'm pretty sure the trains/trams that currently take people to and from the airside and landside terminals will be removed.

In fact, I believe the cost of operating them was listed as one of the main reasons why combining the airport into one larger terminal is a preferred option from a financial standpoint, and the last paragraph at the Wikipedia link that Minivan shared reads:

The proposed remodeling project for the airport, unveiled in 2017, would take the trams out of service permanently, as the proposed Landside Terminal is permanently connected to the existing Airside Terminal.
