What the latest on the Aerotrain underground station, and access to the C/D terminals & future (F?) terminals?

Some posts say that the station was supposed to split the distance between the C/D terminals & future F terminals. To save money only one station was built. But even now the walk from the station to the C/D terminal is super long.

Other post say that a new C/D terminal will be built over the current station location.

Thanks in advance, Marc
