I'm pretty confident I won't be. You're daydreaming if you think Nintendo is going that high spec. And for what reason would they do that? You honestly think they're gonna waltz in during the middle of the generation and expect core gamers to jump ship to the NX? These people aren't interested in Nintendo and Nintendo isn't interested in them. They wanna fish in that big blue ocean again like they did with the Wii and the DS. You just need acceptable performance for that, anything more is a waste of time and money.
I'm pretty confident Nintendo wants and needs third party support since they learned they can't support their consoles on their own. To do that, they need to at least match the current consoles in specs and support current engines. They've already got Unity and Unreal 4, and are part of the Vulkan initiative. There's still plenty of gamers who haven't upgraded yet, or want a Nintendo console, or are fine owning multiple consoles.
You need to think of the long game here. Nintendo isn't going to win this gen with the NX launching three years later but it will build a foundation. It'll me the first to have online on par with the others, cloud based accounts and gaming, an achievement system, free online, and a message to consumers that can get the latest games on our platforms now. The message might take awhile to kick in, and Nintendo might not reap the benefits until NX2, but you gotta start somewhere.
The NX is going to be at minimum, XB1 levels of power, which should be cheap to make since its 2011 tech and if costs about $350 to make a profit from, while not being tied to TV features and Kinect.
