Yes, I do not expect them to rise at CCV or Poly, but the increase of OTU price has a ripple effect on other prices. It will drive more demand to rentals, which will raise their asking prices. This in turn will make resale look like a better deal, which will raise its prices.
Disney can then raise the prices of their sold out resorts, both to increase their margins on ROFR, and more importantly, drive sales to their soon to be 3 resorts that need to get sold out. $176-$180 a point does not sound so bad when BLT direct is going for $195 and BCV resale is $150. Also, people have shown that they are willing to pay $185/pt at BLT, as is evidenced by 4700 points being sold direct in August.
This is just wild speculation, so feel free to poke all the holes in it you want. There are also a lot of moving pieces in place, such as the strength of the economy, that can easily affect where things go.
The raising of OTU points by $2 a point does line up with the other steps happening, though.
