I don't see the purpose of these super high quality trailers that have nothing to do with ingame-graphics or actual gameplay. Sure, they look good but they always make the game look way uglier than it truly is.
Well, here some actual gameplay with some extra information.

My opinion:
Looks good, way better than the pathetic first game of this new franchise. Maybe Ubisoft actually learned from their previous mistakes, but I'll be careful and rather observe what this game will look and feel like when it is released. I don't want to get so much disappointed again like when the first Watch Dogs came out.
