I don`t think that`s Nintendo`s plan.
They do intend to have a streamline production of SW and i think they will, while having a portable device and a home console (they confirmed that both are being "made" already), Nintendo will make them work together.
My guess is that by sharing the same architecture (which might save them money on R&D and actual product manufacturing) and not a massive difference in power, they can easily make one game that works on both HWs.
The recent confirmation of an account system would allow this.
Not only would this allow them to save money and keep prices cheap (assuming that sharing the same architecture would allow that, of course), it would give them enough room to not overexpose their franchises (instead of 2 marios for handhelds and 2 for home consoles, one at launch and another 2 years later, for example), it would allow for creating/reviving franchises and be more creative.
Honestly, to me that`s what Nintendo is planning.
Because, just sharing the same game between platforms would mean that those who buy 2 Nintendo platforms to get different Marios, Zeldas, etc., would only buy one, thus, losing money.
having them work alone and as one is the incentive that people need to buy both consoles.
Imagine a SKU for 400$ where you get a handheld and a Home Console.
