Honestly, the xone and PS4 having mildly disappointing cpu power makes it possible to stay competitive with their NX platform. If what you say is true, and NX cpu power is indeed slightly above xone, what mobile cpu tech may apply? Maybe one of the pro's (Fourth Storm, blu, thraktor etc.) can chime in again, although they have discussed it previously.
If "industry-leading" chips ( which was a rumour) refers to the mobile cpu tech, and Nintendo has indeed the same cpu tech in their handheld and console, they have an advantage. In turn, Nintendo might probably come back on their statement of not having a shared library; I fully expect them to. It is the way forward, if Nintendo still wants to design it's own hardware in the future, aside from their mobile division.
If I were Nintendo I would launch the handheld first, somewhere in 2017. Why? Because of the following;
-Easy porting of their mobile offerings (why not?!?) on NX handheld as well.
-Easier to attract (Japanese) third parties as they have proven in the past.
-Lower risk and cheaper software to develop (handheld titles like advance wars, monster hunter, Pokemon, etc. Basically huge names/system sellers).
-Their handhelds have historically outsold their consoles, thus creating a safer ecosystem (online platform, e-shop content, username, branding etc.).
- NX console launches subsequently in 2018 ; with the existing library it already has the software/userbase in place, but with the added resolution, those games become somewhat more enticing to play. Also, it might launch with a few heavy hitters, which where previously only on consoles; like Pikmin 4, zelda and Metroid. By launching these expensive ( which take longer and are more expensive to develop)games with a console in an already established ecosystem (because NX handheld will play them in lower resolution and is already 1+ year on the market 21) of say 10 million users, you greatly reduce the risk of a struggling console with expensive games.
- Avoiding psvr buzz launch, while expecting Sony/ms to "really" upgrade sometime in 2021.
- Setting up account system, infrastructure etc. takes time, NX console needs to launch in perfect conditions in order to avoid "bad press" and handheld usually can get away for a time without stuff not yet being finished.
Yes, I am of the believe NX will not launch in 2016, but sometime in 2017, maybe late summer/ July. Then NX halfway 2018 or maybe October 2017.
