The only thing we know for sure about the NX is that it will receive a port of the Zelda Wii U and it will be delayed to have more software titles during its launch year according to Nintendo. Every other speculation we have or will see about the NX is exactly that - speculation. However some speculations make more sense than other and are more likely to be true. As a result, dismissing other speculation with another speculation can be tricky because some speculations are popular and accepted to be true because many people want them to be true. However, these speculations were only speculations in the first place and nothing more.
With that said, here are some popular speculations about the NX that is releasing on March 2017:
1. The NX will have a screen on its controller. Whether that's the default controller is not completely agreed upon yet.
2. The NX is most likely a home console or acts like one. Nintendo continuig to support the 3DS while the Wii U is forecasted with 800k sales until next March shows Nintendo's faith in supporting it. So we can guess it's replacing the Wii U and not the 3DS. The system can also run Zelda Wii U which is a home console game. We have no idea what kind of specs Nintendo wants in their next handheld so its safer to guess the NX is a home console.
3. The NX will connect to the next Nintendo handheld like they are "brothers." This is a paraphrasing of what Iwata said last February when describing how it will interact with the next Nintendo handheld. This is speculatiom because we don't know if things have changed, but since Iwata has said this, it is likely to be true.
4. The NX will absorbs Wii U's architecture. This is another statement Iwata made last February. He did not specify any further and we don't know what he exactly means. Did he means so as literal sense or a general sense? Again, we don't know if this will still happen.
5. There are many patents that were published after the reveal of the NX. But because not all patents become real products, speculation about the NX based on them is not entirely credible. However, there is a possibility some of these will be used. The question is which one. There were a lot of patents published so I won't list all of them. Just look them up yourself and see.
