It will be very confusing.
There is already "Fort Wilderness" "Wilderness Lodge" and "Villas Wilderness" now they are going to come up something like "Cabin Wilderness" or "Wilderness Bungalow" all keeping the same theme... people may think it's the same thing. I used to think Fort Wilderness and Wilderness Lodge are the same place, just one has a camp and the other has hotel... but they are practically independent, with their own bus stops / routes, etc.
If they do not allow the new owner from VWL2 to book VWL1 at 11 months, then it might affect their sale. Potential buyers may think, I am paying full price and you allow me to book half a resort? If they allow the VWL1 and VWL2 merging by offering an upgrade, then VWL1 resale price will go from current $90 to $150 overnight. But how can they force everyone to upgrade?
I think the owners of VWL1 are watching very carefully. I think there may be a class action lawsuit if
DVC takes away VWL1 land or facilities to make VWL2 without any compensation to VWL1 owners.
