I don't think he's wrong.
People are dogging what he says too much just to hate. He isn't being a troll. PS4 Pro clearly had very different design ambitions from the XBO-X, and that's okay. It's not worse. It's a different system catering to a different demographic.
He's not saying it can't compete, he's saying it's not the same thing, because it's not. XBO-X is a console for people who want something closer to PC performance without the headache of a PC. That never was what the PS4 Pro was trying to be. PS4 Pro was just trying to be a better PS4 for VR.
So much needless demonization in this thread.
