70% of the fourth trailer was in-game footage, there was just no HUD visible and the cameras were being controller by R*.
But of course, these are in-game, you don't see HUDs in cut-scenes in any game.
My only concern is not being able to see your weapons. I hope I can view how much ammo I have and what weapon is equipped but not just so when you select it appears then fades, I'd rather it stayed there or when your using it anyway.
