What I can summarise so far is that there will be two devices. Home console and Handheld device. They will be different machines, but they can play roughly the same games. There won't be 1 game SKU that works on both, each will have its own library of games. Iwata mentions porting.
Controls will be about the same for both devices. A screen like the Wii U game pad is almost definitely going to be in, guessing from the port of Mario Maker that is said to be in the works for NX. Mario Maker doesn't work with a standard controller in edit mode, and would be really cumbersome if they tried to work it in. Zelda U is likely to use Gamepad touch screen features too.
The thing about the architecture Iwata is talking about is the OS layer side of things. It will make porting extremely easy and cheap, that it makes sense to release a port on the other device anyway.
There would still be work to reduce asset detail for the handheld version but if it's high spec enough, maybe just a lower resolution would be enough.
Nvidia is involved, possibly only one of the devices. Maybe both.
Iwata has said in the past it's not going to be a hybrid.
