The Points at the DVC resorts are set on the point charts for that resort. Disney has the right to modify different nights during the year with the caveat that if they increase one night's points by, for example, 5 points, then they decrease another night's points by 5 somewhere else in the year. Boardwalk, Wilderness, Beach Club and AK Villas are more points per night for accomodations than OKW and Saratoga Springs.
So, if your question is will future villas developments charge more points per night during the year. Yes, that's possible.
