The real news was that there was no other project announced other than DLT and Poly and no new info on Poly. The name has always been PV for the resort. That does not predict the
DVC association status.
I think the best predictor of it being in the same association as PVB is DVC not announcing that it is a new association. I would think they would highlight that in every sales pitch that PV2 was a different association to help create FOMO and sell direct points at WDW.
If it was going to be the same association I would not announce it and let the rumor mill of a separate association drive some sales to direct until they had to announce it.
