As we're revewing the linked-to footage, we can only comment on that, no? If they show a later video with hundreds of enemies in epic scope and still with this detail, opinions can be reevaluated. At the moment, the video footage that spurred the comment 'this is the best looking game ever' is very different in scope to other titles, so on technical grounds there's not really an objective argument there.
Multiplayer, incidentally, also seems to be limited to 8 players ...
