Fair enough, I believe you are right.
Here is my personal guess as to what will happen....
The 6.2 will be gone, I think it was only brought to market to phase out the v10.
I think the 5.0 will be changed a bit into a ecoboost type engine, as it has been pointed out that some of the castings have provisions for such use in the future.

So I think that the f150 options will be 3.7 v6, 3.5 ecoboost, or 5.0 ecoboost for the raptor.
Ford ditched the ranger, because they speculated the only people that bought them wanted low budget trucks, so I expect they will use the 3.7 a lot on XL models.
Then for the super duty line up, I bet either 6.7 diesel, or 5.0 ecoboost will be the options.


I could be wrong though.
In fact, most of the time, I am wrong.
