All New 2019 Silverado Reveal

Cool truck for sure and now another Dmax is hitting the street! With Inline 6 diesel that should be an impressive engine. Looking forward for the upcoming test for sure on that truck. Now I'm curios about the GM 6.0. They just mentioned the 5.3 and 6.2 only as a refresh. I know that they were discussing the 1/2 ton market only it seems, but does anyone know the plans for the HD engines?
