All of those said Series X/PC only. The cross-gen stuff listed Xbox One at the end of the trailer.
How did this happen? For months we've been hearing how the Series X would have no exclusives and everything is cross-gen.
Almost everything mentioned is in pre-production or incredibly early (maybe Forza will make it out quickly anyway, as it has in the past). By the time they come out, it's likely the Xbox One will be put to pasture and Xcloud will be upgraded to Series X levels. There'll be no need for compatibility.
