PS4 was sold out at 199$ pretty damn quick like 2 days, so depending how many sony wants to sell it can make a bigger impact. then you have games like blops 3, RDR2, spider man, and GOW, so yea, this year's holidays should destroy 2017 holiday easily.
I know it was, that doesnt automatically mean it will have a bigger affect this year.
Of course those games you listed will be huge but every year has huge games during the holidays so i dont really see much of a difference there.
