Each resort has millions of total
DVC points any cost increase or decrease is spread out over those millions of points. For example BLT has 5.73 Million DVC points in it's system. This won't cause any significant movement in the annual dues. A penny more would generate 57K.
I wouldn't count on anything before June at this point. The discussion is for another thread, but the DVC system is built for a long period of unused points. It keeps running with very high occupancy. I have no idea what they could do to fix it either. There's going to be a massive glut of points that need to be used in a short timeframe, and it's going to cause problems.
