They'll have this exact tech demo running on a Series X internally. It would be years away, but it would be interesting to see it leak out one day and see if it is a bit better or a lot better on Series X.
Instead I think it'll be 4 years before we see truly hardware bending exclusives from both console makers we can put besides each other and go 'WOW'.
