I'm gonna need a source on him admitting to spreading FUD, AFAIK he never admited to such thing.
His commentary hasn't been debunked, and CoD being 4k/60FPS doesn't debunk that. He never said 4k/60FPS cannot be achieved on PS5, only he heard that people making multiplatform games are struggling to get 4k/60FPS on their respective titles, which unlike CoD yesterday, might not be crossgen, and actual next gen/high fidelity games, which is trickier to get running at 4k/60FPS compared to crossgen like CoD
That isn't commentary though. That's him saying something that *allegedly* someone else told him, it's nothing to write home about, but the dude is trying to say that 1080p/60fps is set in stone for some big title he almost certainly has no hand involved with himself. The doubt speaks for itself.. now if he were to provide some evidence AKA actually leak something, then there'd be less of a problem believing him (which is common sense).
