You have the author of the video (and most of everyone else particularly fixated on just a single item at best or astroturfing at worst) saying that he does not think it was any case of overpromising to mislead people and there was an artistic and manpower related decision to allow the game to come out

... also that the game has not been "downgraded", but overall it has been improved graphically over any version shown before it.
Amazing that the attack was made over resolution ("game looks softer, resolution is surely down!!!") when the resolution has actually been improved and not just a tiny bit
