I'm well aware of that, however I harbour some doubt as to whether the spotter is getting all the details right, or if he has not seen the entire ship in such detail and is taking certain liberties.
Specifically, I think the bow and the front half of the ship's design and proportions are probably fairly accurate considering the location from where the spotter is likely viewing the ship from. But I'm not so sure about the rest of the amidships and aft portion of the ship, as I imagine those parts of the ship would be fairly difficult to see from the spotter's location.
Of course it's possible the spotter has gotten all of it right and he may be able to see everything that he's depicted, but in my experience I think it's sensible to exercise some caution regarding details of an upcoming ship's or aircraft's design until pictures of the whole thing emerge. I still remember the lead up to J-20, Y-20 and 052D about certain design details that were still yet to be settled and only definitively closed once we got clear pictures of the whole thing.
