On the gaming side:
"Our future platform will connect with our consumers based on accounts, not devices." - Iwata.
"As I just illustrated, we will manage our relationships with our consumers through NNIDs in a uniform manner, and connecting with our consumers through NNIDs will precisely be our new definition of a Nintendo platform.
In other words, our platform will not be bound to physical hardware and, instead, will be virtualized." - Iwata
About the QoL:
"Including the hardware that will enable such an idea, we will aim to establish a blue ocean."
"we expect the QOL-improving platform to provide us with new themes which we can then turn into games that operate on our future video game platforms, too."
Although these quotes reinforce what the OP is saying, the NNID integration is just an hypothesis.
Will that carry into the new HW? So far there`s no indication that it will, only that the new "platform" will pull it`s users into the future HH and HC.
How will they do this? Who knows. Maybe it will really be the NNID, maybe they`ll just communicate in another way with it`s the QoL platform users.
