4K, HDR and the Xbox Scorpio vs. PS4 Pro

StrikeA from TGA says "So, is the best we can expect from both the Pro and Scorpio 4K HDR gaming at 30fps, with 1080p games running at 60fps? Microsoft and Sony may have some tricks up their sleeves but as it stands I think that’s the best we’ll be getting, unless of course components in the Pro and Scorpio will be upgradable? Sony haven’t mentioned this so far, but Microsoft did say that “we think the future is without console generations”. Perhaps we’ll see 4K HDR 60fps once we’ve upgraded the GPU in our Scorpios?"
