This is all very confusing to me, as it sounds like they targeting the wrong audience with the wrong gaming options.
120 fps sounds like it should be aimed at a more hardcore group of people, having it on the series s to me sounds rather redundant.
The series x, being so much more powerful, is in essence the hardcore gaming system, 120 fps sounds perfect for it. I would imagine the cutbacks would be minimal.
The series s is the mom-and-pop option that buy jimmy a cheap console for Xmas.
Does she really need a 120 fps.
