Not sure what the hubbub is about. The current rod design has given good service since 2011. Plenty of those trucks are running well above stock power levels on stock pistons and rods. This looks like getting tooled up for a power increase to me but unnecessary at the current power levels.
As speculated, this isn't an issue with the current 6.7's that aren't tuned. It's just a preparatory move to get ready for the 2019 power bump.
That makes no sense to me. That new connecting rod is presumably more expensive to make. Ford would have no reason to start spending more on engines making the same output as Job 1 trucks...unless they are seeing a problem. I can't think of any time in the past Ford has installed heavy-duty engine components "in preparation" for some future engine output. I'm extremely doubtful Ford will do a reflash of current engines for more power...there's no need at all. To beat RAM by 5 lb-ft? Ridiculous.
My theory is that perhaps a few 2017 engines have failed with rod issues; Ford studied it and saw a problem that could become widespread over time. Thus, a stronger part starting with Job 2 to stem the potential number of affected trucks.
They may figure most Job 1 trucks will likely make it past the 100k warranty, and some may make it a lot further than that. Replacing rods is very expensive.
But that's just my theory and could be completely wrong.

There have been a few rod and crank failures in the 6.7. However it has not been widespread or endemic to the 6.7.
I agree that Ford, or any other manufacturer, would not spend money if they didn't anticipate some kind of problem.
The beam looks wider in one direction but thinner in the other.
I would not be surprised if the weight is the same between
the two like Ford just moved material around.
