In my view, when it comes to PS4, a permanent price cut should be right around the corner. The fact that it's still selling at these levels at $300 & $350 respectively is great. But, if they maintain that price in 2019, I think we're going to see sales drop considerably. The Slim and Pro models are over 2 years old at this point, the 1 TB for the Slim is over a year and half at that price point. They should go down to $249 & $349, permanently no later than Q1 2019.
