At the 53 second mark we are shown a laser sight that is still turned on for an Awoken's weapon. I know its a stretch but if Bungie placed it in a video, and they know how much the community picks apart all videos and footage I would hope there'd be some truth to what we see. I think it'd be a nice small addition to include laser sights on some weapons, as either part of the the first perk line on a weapon, or as a toggled option. Again, it may be a stretch or could be coughed up to only for the Awoken, but having laser sights, could be pretty cool.
