I highly doubt the new 1500 will have a low range, I think the steel drive transmission is what it is and Tow / Haul is as close as it will come to a low range. That said I wish they would improve several short comings that piss people off.
1. Side mirrors should be standard
2. 4 speakers should be standard
3. Front camera should be standard
4. 32" tires should be standard
5. Turn signals and a horn should be standard
6. Radio reception SUCKS and it shouldn't
7. Ride Command is now the dated screen in the industry, needs upgraded
8. Leaking windshields, clunking rear ends, dust and heat infiltration ALL need greatly reduced.
Instead, what we will likely get are some new colors, maybe cooled seats, or something else that's makes it cost more and fail more often.
