How did you come to the conclusion that it is "probably" more powerful than XBO S? I mean, it would be nice if true when it's in the docking station but nothing we saw hints at more power as XBO S. We saw some games looking worse as XBO S games (technically), a port of a last gen game and a sport game.
If they would have shown some recent PS4 game with same settings and 1080p but we didn't see that yet.
