Pro consoles aren't going to solve this.
The mid-Gen updates last Gen didn't solve this issue, all it did was allow developers to add more bells and whistles while not addressing overall performance. When this Gen came out, everyone was convinced we had put 30fps behind us because it was a step up from the PS4 Pro and Xbox One X who were already sliding into 30fps territory.
Three years into this generation where
4k/120 was a selling point of both consoles, we're back to 30fps with graphical bells and whistles taking developer's priorities over 60fps and good texture/IQ.
Anyone thinking it's going to be any different with an overpriced "pro" console is setting themselves up for disappointment. Just spend another $600+ - I'm sure
THIS time you'll get the amazing graphics they promise.
