You don’t understand, by not being tied to HDD developers can make games in new ways. Again they have claimed textures can be read so fast they can be processed directly from the SSD meaning they don’t have to be loaded from the HDD into RAM freeing up the RAM to be used in other ways. That can make a HUGE difference in the way games can be developed.
And let’s say the Zen CPU can support 100 AI/enemies/NPCs but the Jaguar can only support 20, both versions of the game need to be limited to 20 so players can play together.
Game development isn’t just graphical sliders.
I’ll give you an example, before 2013 nearly every game was made to run on 32-bit systems which limited the amount of RAM to 4GB (both system and GPU combined) that games could use. When this gen came out the consoles used 64-bit exclusively and now nearly all games on PC also finally moved to 64-bit. That’s why we can have 4k gaming, because 64-bit allowed for 8 and 12 GB of RAM on the consoles and essentially unlimited on PC. (16 exabytes)
Again people (probably even yourself before Microsoft made this decision) were excited not only for next gen consoles but gaming in general because they hoped that SSD would finally become the baseline for modern games and we would have another jump like the one from 32-bit to 64-bit.
Unfortunately, Microsoft is opening the door for gaming to stay limited by old hardware.
And if what I am saying isn’t correct, then what is going to happen after two years? If the SX can’t do anything the xbone can then why have a two year limit at all? Obviously the two year limit implies that they will eventually start making games that can’t run on the older hardware.
