Portals have been in use since 4th edition and are even more in use in 5th edition and I doubt Larian is going to change that.
It depends ...
If by "change" you mean delete portals and act like they was never there ... then yes, you are not alone who doubt.
If by "change" you mean change the perspective how world see portals, and taking them to concideration ... that is entirely in their hands.
