Warthog turret different to Mega Construx version?

So I don’t know if the Warthog in the gameplay demo was final but. When I saw the Mega Construx Warthog I got super hyped because the turret was the classic rounded esc design that the Bungie Era hog had and was combined with the more combat ready current era Hog and I loved it. But in the Infinite demo it was a complete reverse. TheThe hog was missing the bullbars on the sitheand the turret was the square/blocky turret of the current era Hog. So unless there’s multiple types of Warthogs in the game (like how there is multiple types of Grunts). I know it’s a tiny thing but I really loved the idea of the turret being the classic design and the rest being current design.
