Watched a review of the trailer today, and the commentator made a good point. You just KNOW a lot of what you are seeing are CG action set pieces now (cars whizzing by, etc). While the original trilogy used blue screen and models/miniatures, a lot of the vehicles were real and filmed on location for the stunts. There was still a physicality to them. Having big set pieces that are impossible otherwise just screams super-hero film nowadays. One thing IJ is NOT, is a super hero.
Knowing that Ford is 80 IRL (and Indy is 70 in this film), you can't help but realize that it's NOT Ford doing a lot of the stunts this time around. Which makes sense, given his age (and the fact that he had a leg injury SW:TFA and suffered a shoulder injury during IJ: TDOD).
