The recent addition of further units in the DVC inventory (which were in fact ones in Kidani) does not determine which rooms DVC members can actually stay in. All rooms were available for occupancy by DVC members even before the addition.
The way it works when DVC is selling resort units is as follows. Members get to reserve that portion of reservable time in the resort that is represented by the portion of the resort that has been sold. In other words, if, for example, AKV is about 75% sold, that would mean members can resereve about 75% of the total available reservation time for the resort in all rooms and Disney gets to rent the rest of the avaialble time for those rooms.
