Could a 7.3 EcoBoost turbocharger kit be far behind?

Why ? This is a TRUCK engine. Truckers (or the people who buy the trucks) want the "best bang for the buck" from initial purchase through maintenance with a long life.

Supercharging get instantaneous boost. Turbo, irregardless of how well it is done, still has some lag.

Direct injection does very little to improve power or fuel economy. The 5.0L "Coyote" engine now has 16 injectors, 8 direct, 8 port. Most of the time it operates on the 8 port injectors.

Unlike superchargers, turbos make more power in lower rpms while supercharged generally make it in higher rpm ranges. It is not just about how much, but when especially when it comes to towing. As far as turbo lag, it is only a major issue when you go wide open throttle and not when you are under load like in a towing application. So when it comes to towing in a truck, turbos are the best thing to have. When it comes to going fast at high rpms with a simple set up, superchargers are the way to go.

Direct injection also does a good deal to increase fuel economy because it allows the engine to operate at higher compression ratios without knocking. A direct injected gas engine can run up to 2:1 higher ratio than a port injected engine. Hence the reason why the direct injected 2018+ coyote has a higher compression ratio than the older port injected one. Higher compression ratios increase the efficiency of an engine. The port injection is only added to the coyote because of emissions. However, the problem is that direct injection and higher compression ratios also increase power and people tend to like to use the added power.
