Thinking about Def
I know that this has been proven to be a much more reliable way to manage the emissions systems than on my 09' pre def Cummins for example but what happens in a couple of years when/if the manufacture...

Not a fan REGEN systems in general. I've have driven trucks with DEF systems since they hit the market. Most issues we have with our trucks are Regen System related. Either the DEF dosing valve malfunctions, the sensor tubes or DPF filters in the EGR system clogging with soot or any other list of electrical/valve issues.
DEF has nothing to do with the regen system. Two separate systems for two different types of emissions... They do interact to a point, but even the pre DEF trucks use DPF, and they are less reliable that the DEF/DPF ones
You're splitting hairs. While technically The EGR is the front half of the exhaust system and the DEF/catalytic converter of the last half of the exhaust system it's all EPA's garbage that messes up an engine that ran reliably for years and now spends ridiculous amounts of time in the shop. Stop by a heavy duty diesel shop and ask how much business is related to exhaust system issues. It's driven up the shop costs for all trucking company.
Enjoy your new engine I'll rebuild my older engine and come out ahead.
