True, if MS wanted to wow people and get them excited for next gen, they should have followed Sony's playbook. The only thing is that they've been pretty clear about their strategy and don't want to be in another platform war with Sony. MS's strategy is a lot more about building GP subscribers through a ton of different devices (including the Xone) as their end game is reaching billions of mobile gamers through Cloud gaming. It's a very ambitious strategy that does make total sense from a business standpoint for MS. However, it will also be a marketing nightmare for selling a next gen console. 

In the end, both companies pretty much showed what they promised. Sony will be pushing next gen graphics and want people to migrate asap, while MS was being more consumer friendly and showed a bunch of smaller GP titles that won't require people to upgrade. I got a feeling we'll be seeing the same thing in July for their 1st party games, except that they'll have some bigger franchises like Halo and Forza with an "optimized for Series X" logo.

I think you are forgetting we are talking about Sony :)  And this demo was done 7 months before PS5 release.  Wait untill Santa Monica, GG, etc push PS5 to its limit and you will quote yourself again on this :D

 You are not ready to see what XSX and PS5 can do if fully maxed out, righ now; but like any new generation, we will need some time.

You're probably right. The biggest take away is that Sony's SSD tech isn't just there for giggles and does a lot more than just shaving off a couple of seconds of loading time. It's going to be interesting to see what Sony's 1st party studios can do with it with their own propitiatory engines.

Despite You ignoring it, my point still stands. There is fraction of the fraction of one percent PC users who has multi SSDs in RAID0, what makes them irrelevant. Mainstream is what matters. There is one more thing. PS5 is equipped with controller with 12 Direct Memory Access channels, not to mention hardware compression/decompression, coherency management etc. All that together makes it a top solution at the moment. Not only transfer speeds. 

That's correct , PC will relied more on system ram , Vega GPU has what it called HBCC , i believe RDNA 2 will feature this costume to be available on the GPU and Nvidia will relied on more VRAM and some sort of bigger L chace .

But it still need to fill that 16 GB VRAM on the fly in less then a second , i bet 64 GB or 128 GB DDR4 is still not enough unless some assets are compress and GPU raw power help with the decompression.

Playstation 5 can't guarantee 4k, 60fps though. PC can do it.

The point is refuted, you just don't like it, the number of users are ultimately irrelevant.
We are talking in purely technical superiority terms here and the PC still has a significant edge over next-gen consoles.

The PC isn't limited to just an 8-core CPU and 16GB of Ram, It's not limited to 5.5GB/s of SSD bandwidth, it's not limited to a single RDNA2 GPU, it's not limited to just 4k.

Do you even know what DMA is? Do you even know if the PC uses hardware compression and decompression? Do you actually understand what coherency actually means in a gaming aspect?

The more data you store in memory, the less that needs to be streamed in, which means a reduction in I/O transfers, so you need less bandwidth.

In saying that, the PC doesn't stand still, there is some interesting SSD developments happening at the moment and the Playstation 5 isn't even out yet.

Well even PCs can warranty 4k60fps for all games coming out.

If you invest in the hardware, you can do 4k, 60fps across every game one way or another.

On console, you don't have such a choice. - Even the "4k twins" . - Aka. Xbox One X and Playstation 4 couldn't guarantee 4k... At the end, developers made decisions to sacrifice resolution to bolster other aspects of their games like framerates or effects.

The difference with PC is the individual user gets to make that choice, not the developer, not the console manufacturer. - Can't run a game at 4k today? Then upgrade your PC tomorrow and you can. - There are a few games on Xbox One X which will only operate at 720P because developers didn't patch in higher resolution support, meaning that new shiny hardware did nothing.

It's also a little bit of a smirk-situation, pubslishers/developers repackage and resell the same old games the following generation as a "remaster" to try and take advantage of faster hardware, which often is just a resolution/framerate bump. - That kind of support exists for free on the PC the day the game releases, you don't need to rebuy the game.

I want to reinforce the "all games", because I remember seeing threads on VGC were it was mentioned that even very beefy PCs weren't running 4k60fps for some games, not saying the fault is of the PC lack of strength (that as you say in many threads you solve by putting even better HW) but problems on the code itself (perhaps on those threads they were just talking about regular arrangements like at most a Titan with normal SSD and compatible RAM instead of a very exotic exagerated setup).

PC hardware doesn't stop evolving. High-end hardware of today will eventually be low-end hardware tomorrow.

Crysis for example was a struggle to even run at 720P on PC when it was released with the fastest hardware available, today a low-end notebook is capable of running the game at 720P... And decent hardware can run that game at 4k.

PC and how the graphics in games can continuously improve on PC as new hardware comes available, especially when you start injecting new graphics effects/modding and so forth.
