2020 6.7 Power Stroke w/Steel Pistons
Here's a video from Mr Truck. He missed it, but the new Power Stroke will have Mahle Steel pistons. This should make this engine platform good for an easy 1 million miles. Link

The link also said that the steel pistons could have tighter clearances and since the cylinder wall and piston expanded at about the same rate there would be less cylinder wear.
It sounds like Ford is going the extra mile to make these engines more durable but only time will tell for sure.
100K dependability towing at the upper ratings is more of a concern.
