true that, its mere speculation for now...
what i'm 100% sure wont happen is OINP raising bar to 450 directly, from 400...
Lets say they raise it to 450, and average scores after this is around 475.... how many you think will pay $1500 to get nomination, when if they try harder in ielts or get better experience they can directly apply for ITA... what i'm saying is between 450-475 there are not many candidates who will go for OINP
i think it will be raised, but probably to 420 or 425, that will give them enough room to play with... what i would strongly suggest also is to have all documents ready before hand, becoz this time the OINP quota will fill a LOT quicker than before... it will be 9 months since OINP stopped issuing PT, and in this time a lot of candidates have entered the pool with 400> scores... so quota will fill quicker.
TBH what i'm really afraid is if they come up with NOC based quota instead of the score based quota, that will pretty much end hopes for a lot of candidates
