News flash for you

Many developers, and even more publishers, are baffoons who release games too early and without proper optimization. Adding another set of specs to optimize for, only makes it harder and more time consuming for the devs to achieve their goals, and as a result, the lower set of specs will suffer. PC gaming is a great example of how to get the absolute minimum out of your hardware. Consoles, as they are now, are the opposite. Less wasteful.
The big shots are the ones determining the direction of the game, and where to allocate ressources. If the baseline specifications of consoles, which as far as I'm aware are the biggest source of income for triple A developers, goes up, then those big shots will deem it necessary to put more ressources into the game looking good. And as such, we continue the trend of focusing on graphics over anything else. And that wouldn't bother me if we hadn't already achieved close to photo realism in graphics. But when graphics are as good as they are now, I frankly find it idiotic to continue to pretty much neglect all other aspects of what makes a game great.
Furthermore, the idea that "regular" PS4 games would continue to be well optimized it hopelessly naive in my opinion. If anything, the last many years should show you just how horribly wrong things can go when developers get caught up in achieving graphical goals. And publishers have shown time and time again that they have no problem with releasing poorly optimized and outright broken games.
