There will be tons of misunderstanding about this. Iwata only mentioned the NX to counter this but oh well. There will be gaming applications for smartphones by Nintendo. That´s the big news here. You will have a unified account on everything that´s avaiable - that´s the other one.
What you won´t get is unified games. On the contrary. Both parties mentioned the importance of IPs. Iwata said it word by word that software has to be unique to the hardware to not damage the IP with bad controls or sluggish performance.
No ports. Unique software. Nintendo still doing a dedicated system, No hybrid.
The market will decide if it stays that way but thats where we are now.
Nintendo in 2017:
- QoL business: health, education. Whatever. Same shared account. Unique hardware.
- Dedicated consoles and handhelds. Yes both. At least one more time. Iwata said as much in this very year. No hybrid.
- Smart devices. Unique Nintendo software with well known IPs on smart devices. Thats new. Different software than on their own hardware, shared IPs to boost recognition.
That´s it and thats huge enough.
