All that applied when RIV went on sale, yet they still chose to restrict the points. There were clearly other motivations in play besides selling the points as fast as they could. They believed they'd make more profit in the long run on restricted points vs non-restricted. Whether it's had the effect they hoped for, none of us can say. Probably hard to even measure it since all of Disney shut down right after it opened.
If they still feel restricted points are the best strategy going forward, I don't see how they would pass up the chance to create 5 million more of them. I haven't seen anything that makes me think they have reconsidered their strategy, but who knows. Personally I'll be shocked if Poly2 isn't separate, but they've shocked me before
