Will GM ever return to the medium-duty large truck market? (I.e.: C4500, C5500, C6500, C7500)?

GM bailed on this market in 2010(ish). And with the success of Ford implementing it's Powerstroke Diesel into their F-650 and F-750, I can't help but wonder if GM will respond in kind with their Duramax Diesel in a new medium-duty platform. Is there anything coming down the pike?

Probably not…

Apparently, there's just not enough demand for trucks in that segment to continue marketing them. Pickups are where the money is, and even THOSE are selling slower these days.

No idea and me crystal ball is broken again

It looks like GM is planning to re-enter the medium sized truck market in 2019 with a Chevrolet 4500 and 5500 series pickup trucks. There's no information at this time about bringing back the bigger Chevy Kodiak/GMC TopKick
