A New Super Duty Engine is Coming...

It would be a hard choice between an EcoBoost and a smaller diesel like you mention. However, I don't know that I would go with a 6.7L in my next F250 because it is just so much more than I need. Save me $4k and grab me an extra couple MPG over the 6.7L and Ford may persuade me to go diesel again.

I don't think the 5.0L would do well in its current form. The 5.0 doesn't have the low-end grunt that the old 5.4L did, and despite the ~300 lb weight loss they are still likely to be heavier than the 1st gen Super Duties.
The 5.0L engines used in F150s are having a startlingly high rate of failures, and we've seen a few longtime members report engine failures at under 100,000 miles. More than a few have been due to cylinder distortion, which leads me to think the base architecture may not be well suited to truck use. Just a SWAG on my part, but more low-end grunt would need to be on order to make it suitable for SD use in my opinion.
I'd really love to see a baby diesel option if it could be done for less cost. I think lots of folks would pay a $4,000 premium for an engine with similar specs to the 5.0L Cummins if it got better mileage than the 6.7.

I've seen a handful of 5.0L failures just in the last few months.

I have no empirical data to back this up, but I've seen enough to make me question how this engine would fare in a heavier chassis.

Just my 2¢ worth but if the 3.5EB was within Super duty truck engine standards Ford would have already dropped the engine into these trucks, the same theory goes towards converting the 5.0 or 6.2 to be an EB. I personally have very little doubt that the Super duty will eventually have an EB engine but it's going to be completely new.

I'm no engineer though, and there are far smarter people than me designing these things. If we see an EcoBoost engine I have no doubt it'll hold up to heavy-duty use, in whichever form that may take.

Maybe the EB could be used in the 250 as a true bridge truck between the 150 and 350. With a 250 you could have slightly higher payload and towing then the 150 all while having a bigger truck that some people want. Then leave the 6.2 and 6.7 to the 350 to make for a better heavy hauler that the working class want.

That's good thinking, but the problem is that Ford is in the business of building a truck that will sell, not just one that will work. People have to be willing to gamble tens of thousands of their hard-earned dollars on this long-term investment that will eventually be out of warranty. There are a LOT of people not sold on the EcoBoost technology in half-ton form. Much less would opt for a V6 in a 7,000+ lb Super Duty out of perception, not necessarily reality.

There are still some minor issues, but not as bad as some of the earlier engines with DI.
FYI, the gen 2 3.5L coming in the Raptor and GT will have dual fuel systems...both port and direct injection.
