Look what just happened this gen. Two extremely under-powered machines were released in 2013 for the sake of keeping the price low enough. And what happened? They were so under-powered and feature less that we are having a mid-gen hardware upgrade because PS4/X1 specs aren`t just good enough to keep up with development evolution.
I think having a 600 USD, or even 700 USD or 750 USD shouldn`t be seem as a bad thing. It`s better to pay this much for a gaming console that will hold up for many years than pay 400 USD for something that isn`t just good enough. Having a high price tag at launch and price cuts with time when the manufacturing costs come down should be the natural path. Have PS4 released with the PS4 Pro specs for 600 USD and with price cuts along the years would have been much better than releasing this mid-gen upgrade that is awful because leave developers with not knowing what to do, PS4 base model will bottleneck PS4 Pro potential, and PS4 Pro potential not being explored it will be harder to justify purchasing it.
I really hope next gen hardware makers go for higher price tags and deliver great machines from the get-go.
