Nah, we haven't seen if this is open world gameplay or not.
What they've added which TR also had is using a "pick" for climbing, and a rope mechanic. I think it's pretty normal to see them try to best each-other.
It's like with shooters, now after Titanfall the theme is "movement". Then COD:AW added new movements with exo-suits and Halo 5 showed off new movements like run & tackle.
