If it gets strongly supported then so be it, but Xbox's gamepass strategy has been reported to be at odds with the handheld market leader and the home console market leader's strategies for game development, and other big publishers might align closer to Nintendo and PlayStation IMO. Companies like Rockstar.First off, Microsoft WILL enforce that mandate until the end of the generation. It's not even a conversation devs will even worry about since they'll be happy to target an audience of millions of Series S owners.
But more importantly, we already have examples of beautiful games that still retain 95% of their visual quality on the Series S. Flight Sim looks spectacular there, as does Forza Horizon 5. Matrix is probably the most next gen thing we've seen running so far... And it runs on the Series S with some cutbacks.
Hellblade 2 and the Coalition's next AAA game will push Best-in-class visuals and will run on the Series S. So no need for you to wait years until the GTA6 reveal.
This whole thing seems like wishful thinking on your part. Even you must know that you're bound to be gravely disappointed when the XSS gets strongly supported to the end of the gen.
I think the XsS is a cynical move and see it being most profitable for devs as MTX sales channel, so obviously I'm not a fan. But am oaky waiting to see what the market decides when GPUs with RT cores get to the £130 price point of moving up PC requirements.
