Somethings worth noting:
Dena has their own platafform(know as mobage). In terms of features, we can expect something similar. Maybe you guys that have a smartphone can share yours experience with it?
Dena will not create something to replace nintendo network, they will replace club nintendo first and foremost. People expecting crosssave, cross-buy and same account on multiple consoles will get disapointed. Nintendo said however, that they were working on something better for nintendo network.
Dena will be like the publisher of nintendo games on mobile space. Nintendo is making the games first and foremost, but things like handling app-purchases will all be sided on Dena. Not sure of who will do the advertising, but considering that nintendo wants the app to work as a advertisiment, i think that advertisiment will be on Dena side.
Neither pokemon shuflle or pokemon go are the game on what nintendo is working. Those are works of the pokemon company first and foremost. So, we are yet to see what nintendo really have in store for us.
It was pretty clear that Dena and nintendo wanted different things while iwata was in charge. Nintendo wanted smartphones more like companion apps, but Dena really wanted the app as product by themselves. Not sure how this thing evolved since iwata's passing. By this i think that is at least secure to say that estabilished IP's will be used.
"Hardware design isn’t about making the most powerful thing you can.
Today most hardware design is left to other companies, but when you make hardware without taking into account the needs of the eventual software developers, you end up with bloated hardware full of pointless excess. From the outset one must consider design from both a hardware and software perspective."
