Edit:
The exact shape of the NX hardware isn’t yet clear. People familiar with the development plans said Nintendo would likely include both a console and at least one mobile unit that could either be used in conjunction with the console or taken on the road for separate use. They also said Nintendo would aim to put industry-leading chips in the NX devices, after criticism that the Wii U’s capabilities didn’t match those of competitors.

From the new Dev portal:
Our new website makes publishing simple
This new website had one goal—to make your lives easier. We’re hard at work making more and better tools to help you self-publish, digitally publish, and publish at retail.
Our plans are big, because yours are
We’ll soon have advanced project tracking and ROM submission, project-based message boards and more, helping you with every step—from concept, to publish, to counting your accolades. And as always, you’ll have the best global developer support team ever, right from the start, making the Nintendo Developer Portal your go-to resource.
Nintendo Dev Interface
Our newest gem in the box is the NDI Client. NDI stands for Nintendo Dev Interface, but it’s really going to be your new best friend. The NDI Client will help make sure you have the optimal development environment on your development system — by downloading and installing it all for you! You can tailor it to the platform you’re developing for, the SDK you want, even the region you’re working in. It allows easy download of all the relevant guidelines and documentation you need to do your work. It even allows you to update the firmware of certain development kits.
