I always get a chuckle out of the theories that Poly2 will be the same association to "fix" the fact that PVB is only studios, or because current owners will be mad they won't have access to the tower at 11 months, or some other thing about keeping current owners happy.
DVC already has their money. Sure they'd like current owners to add on, but I'd wager most of the points sold at a new resort are to new owners. Could be wrong about that, I wonder if that data is available for RIV.
It could end up being the same, but those definitely won't be the reasons.
