No you will not get an Ecoboost 5 litre. Under load they drink fuel(they have them here2 Litre versions) A turbo gas engine is not as realiable as a Diesel , less sturdy construction.
Bull$hit. The Ecoboost 3.5 is every bit as tough as a Diesel. I know, I drive one and with 60k on the clock it's perfectly fine. Diesels have to be tough to stand up to the high compression. Yes they drink fuel when you get on the boost. But a flat out Diesel drinks too. Look at the study you posted - the MPG's for the truck engines are 1-4 MPG better for Diesel.
One of the characteristics of the diesel was torque delivered at very low revs and its general efficiency over Petrol. Common rail and Tubocharging have vastly changed the nature of the diesel engine.
Look at the torque curve for an Ecoboost 3.5 and even the 4 banger Ecoboosts. I know the EB 3.5 is low and flat. Efficiency is because Diesel has more energy per gallon than gas not because of the engine construction. And in theory it's cheaper to make as it's less refined.
