Prediction: Nintendo's 9th gen console to be both home and handheld in one

[JEMC]

That's a very interesting option that presents both benefits and problems.

But the big question would be: the machine would be a handheld console that connects to the TV or a home console whose controller can also function as a handheld? (something like a WiiU but with a GameBoy Advance as its controller something like the Nvidia thing with a PC).

The first option would lead to a machine with a lot more software (all Nintendo studios would work for it) and also a cheaper machine compared to the other option but it would also be less powerful and people could see it just as another handheld, something that could affect their sales when competing with smartphones, tablets, etc. which by the time could be as powerful or even more. Also that would mean that Nintendo would only have 1 device to support them, and if it fails, they could face serious problems.

The second option would also lead to a machine with the same software but fragmented, with some games developed to play with the controller and other to play with both devices. It would also be more expensive as it would have the cost of a home console as well as the cost of the handheld, something that would many people off at least during the first years. The advantages would be that the machine could be as powerful as Nintendo wants, that with a controller that also acts as a handheld Nintendo would still have two devices in the market so if one fails they could still use the other to maintain them, that would also put them in a better position against the competition (both the consoles and mobile devices).

Which direction, if they merge both devices, would they go with?
