Yeah, but both sound similar to me with better wording, but it's probably meNone of the statements on the matter have ever said "it can't be done" to my knowledge. What they have said is something along the lines of "due to technical considerations these features will only be included on next-gen platforms".
If they didn't at release, they simply ignore the console market. If I remember, Series S/X and PS5 was released only a month before and out of stock directly day oneThat's why they released on ps4 and Xbox One in the first place.
But we'll see, but I doubt that we will be able to "know" for sure why "old-gen" can't handle it.
