Fish, below is the a link to the info about phase 2 which will be for model years 2021-2027. Phase 2 is mainly to decrease CO2 and increase fuel economy in 3/4 ton and up vehicles. Since diesels emit less CO2 than gasoline engines, the CO2 requirements will probably effect the gas engines more than the diesel engines.
So in regards in lowering NOx and PM, it looks like there is no more regulations on the horizon. However, we should see HD truck makers start to introduce tech or improve tech in their 3/4 and up vehicles to increase their fuel economy similar to class 1-2a vehicles before.
I am not sure if you can view the link without a subscription.

Heavy-Duty Pickup Trucks and Vans
The commercial pickup and van category includes those vehicles of GVWR from 8,501 to 14,000 lbs that are not regulated under the light-duty GHG/CAFE vehicle regulations. These vehicles must meet corporate average CO2 and fuel economy standards, in an approach similar to that taken for light-duty vehicles, but with different standards for gasoline and diesel vehicles.
The EPA has established CO2 standards in the form of a set of target standard curves, based on a “work factor” that combines a vehicle’s payload, towing capabilities, and whether or not it has 4-wheel drive. The standards phase in with increasing stringency in each model year. The EPA standards include a separate standard to control air conditioning system leakage. NHTSA has set corporate average standards for fuel consumption that are equivalent to EPA‘s standards (though not including the EPA’s air conditioning leakage standard).
At Phase 1, manufacturers were provided with two alternative phase-in approaches. One alternative phased in the final standards at 15-20-40-60-100 percent in model years 2014-2015-2016-2017-2018. The other phased in the final standards at 15-20-67-67-67-100 percent in model years 2014-2015-2016-2017-2018-2019. Phase 2 standards are phased in over model years 2021-2027.
