My Lightning is the best truck I've ever had.... until it's time to tow long distances with the camper. Towing range is the problem. Everywhere else the truck is amazing.
I don't think a 5.7 JT will happen because SAE J2807 prevented the 2.0T and I don't see how shoe-horning a V8 into that little engine bay could be better. But IF it happens I'll be first in line at the dealership.
