There are multiple factors to be considered here.
1) As of now the OINP points are 400 Minimum, there are no announcement or news of the same that they are going to change that.
2) CRS points are getting down, while maintaining stand around 460 - 480 in past couple of months. increasing OINP points to the same level, sub-value their needs.
3) OINP is not the only state offering the PNP, if the points are high and occupations are in demand, there are plenty others offer the perks with lower waiting time, they can't afford to be in this state of situation.
4) It's September, 3 months to go to end 2016, while targets of IRCC is far from achieving, I am sure that new draws will see significant drop in the points as the can't afford low level of migration specially when their citizens are aging.
Yet, we can not say anything for sure, Lets hope for the best. I am in favor of thinking that Points will be reduced than increased in effect of overall; CRS points decreasing.
