If the engine is made by ford than I'm sure they will keep with there long tradition of making POS diesel engines like they have since they scraped the 7.3. I've always been a Ford guy but they really suck at making diesels
The only diesel Ford actually has made for the pickups is the 6.7 from 2011 on up. These are by far the best diesel engines ford has offered in their pickups. The 6.9 7.3 6.0 and 6.4 were all made by Navistar (International). The reason for discontinuing the 7.3 was emissions standards. The 7.3 is not nearly as good as the new ones. It is loud, hard starting, and does not have near the power. They were an excellent engine in their day, but technology has come a long way in the diesel class.
They have been talking about a diesel in the half ton since around 2005. Navistar had one ready to go, but with the disaster of the 6.0 and the resulting split from supplying Ford engines, it never happened. I was at a service school around that time and they were close to releasing it.
