As long as it's better than Witcher 3's, I'll be glad.

When I compare Witcher 3 with Horizon Zero Dawn, on PS4 Pro, it's quite nuts.

Although it's a current generation game, it's still a comparison. We can see, based on that current generation game, how much faster is the loading times. Even though next generation games will be heavier than that, it's still a technical comparison.

Witcher 3 should not be played on a console, and this goes especially so for people that like to utilize quick save. I almost missed out on the game because of this.

Well shit looks better than my computer.  This will come in consumer friendly price of 400 or 500?  Thank god for mass manufacturing.

And for 20 years loading time have been high and in some cases dreadfull - looking at you GTA.

So a faster SSD instead of a slow HDD is a great improvement.

For Sony 1st parties they won't have any need to look at mechanical storage or PC from how what Cerny is pitching so far.

This certainly could be just marketing fluff in top of nothing more than a regular SSD being put into the machine, but I will wait and see before calling it just that. What has me really curious here is that even though they did cherry pick a game that already has really quick load times so that they could achieve a load time less than a second, they did so by a 9X increase in speed. Out of curiosity I looked through several video comparisons of games loading on SSD, and while there were a few bad ones that only got a 1.5X boost, the best range was around a 3.5x boost. To me this says one of 2 things. Either there is some special hardware solution, or (this is sort of answering your question), this game was modified to run differently so that it could load faster.

Many games built based on mechanical drive, games like Assassin's Creed , GTA, Red Dead Redemption are obviously still using loading phase but it was hidden in the gameplay. Even game like The witcher 3 still has loading screen . I am using a Nvme  SSD but it still has 3 to 4 second on loading time. SSD is faster on loading startup screen on windows and PC OS , also for cinema bench and video editing,  but on gaming it's still the same and you obviously lie if you say no loading screen it still have loading time it' s just slightly faster.  Just look at this article https://www.pcgamer.com/how-do-ssds-affect-gaming-performance/

also read this https://techguided.com/ssd-vs-hdd-gaming/. That is the SSD for PC, PC gamer has been using SSD but none of the benefit of the SSD can be implemented on PC because all developer is just thinking like you, just for boating and caching . It will be different if all games are meant to be build using SSD. watch this video  https://www.youtube.com/watch?v=V3AMz-xZ2VM

Btw blast processing on Sega is real actually and the cell also real, for the cloud it's also real but it was translated differently and it was not meant for graphic enhancement but for procedural and persistent physic. 

Not really telling me anything I don't know...

I am not saying Blast Processing, Cell or the Cloud wasn't "real". - They are all technologies that fundamentally exist.
The contention point is that people made those aspects to be something they aren't in order to try and assert their platform choice to be the superior technical choice... When in reality, those technologies didn't really give any particular platform such an edge that it was impossible to run on another platform with similar results.

PC also does benefit from an SSD, in-fact it's baked right into Windows, Game Engines and API's. - Need me to provide some examples?

I think you just stalling the discussion, there has not been any change or whatsoever on PC ssd for past years "FOR GAMES SO FAR ". When you say "API" yes , they have gaming API ready available for PC for long time, but the discussion is about how game developer " utilize it " inside their game engine and their "games" , nit just inside gaming API. Console will make it different it will just be an API it will be for real realize for sure in reality. It will become mainstream thanks to console. like always is tech will improve if it's benefit more people (mainstream)  rather than small group of people (high end user ). 

There has been tons of changes on the PC over the past several year in regards to how it sees storage, Windows Vista and Windows 7 brought a slew of improvements to that end... And Windows 10 took it a step farther.

Direct X's Virtual Texturing also takes full advantage of solid state storage... And there is one engine in particular that leverages that technology extensively.

The point you don't seem to understand is that the storage medium isn't going to change how games operate or run or how they are even developed, there are fundamental design principles that need to be adhered to for various reasons at all levels.

If a game relies more heavily on the streaming of assets, then an SSD can provide a substantial advantage... But a completely new gaming experience it will not bring.
