It's on them to show us the benefits of that 12.28TF + SSD + whatever. Even here, we are the hardcore, audience, people want to ave a reason to buy the new machines to spend every single dollar of extra income we have on it, we want to hype our friends about the new generation of games, etc.
And as I have said many times over, it will be pretty hard to move people away from their PS4s with the same games running at 4K/60fps + some ray tracing sometimes + faster loading times and gamepass (especially when PSNow is a better "deal" that they can access now).
Unless you use the SSD in some manner, the graphical bump will be similar to what you get on PCs with a geforce 2080ti, really nice... but this is not like the game looked overwhelmingly different. The last time we had a console generation we did not only gain benefits from higher resolution and framerate new rendering techniques that gave games a completely new feel were enabled, ou can see it in Sony's ports of PS3 games to the PS4 (TLoU, Uncharted) these games run better, but they still look like PS3 games, nothing close to even day 1 releases like Killzone:SF on the PS4. So if the arguments are not made well enough these consoles will only ever get to run PS4/XB1 compatible games in enhanced mode, like the PRO consoles do now, only more.
I bet they only changed the graphics setting s to match higher PC equivalent settings and build target to Xbox series X at build time and then you have something similar to the benefits offered by the X over the base version--if the X was the base console.
What is not clear is what happens if you pop your existing Xbox one game in a series X machine. Is the new machine really backward compatible? Or is it not? If it really is backward compatible you should be able to play the not enhanced version anyway.
