To be honest it's not a bad idea so long as there's still a traditional NX physical console for those who want that.
But a streaming service from Nintendo could be a game changer because unlike Sony or MS, Nintendo on their own could provide enough value from a streaming service to justify a monthly cost. The problem with things like PS Now is Sony needs third parties and third parties want their cut of the money for offering streaming and it becomes a total clusterfuck quickly.
But y'know for that portion of the audience that simply does not want to pay even $150 for a seperate Nintendo console ... if you could get them in for $99 a pop and they're willing to pay say $12/month for access to Nintendo games ... it may not be a bad way to expand your customer base.
You could even offer it through the PS4 or XB1, the requirement would just be that you have to have the Nintendo controller.
Internet speed is another issue here though, *but* in Japan ultra-high-speed internet is spreading quickly and it wouldn't be so hard given the size of the country to allocate server units locally, so maybe it's an idea Nintendo starts with in Japan and then expands elsewhere as ultra high speed spreads over the years.
It could work like this:
For $89.99 (comes with NX controller + TV receiver) and $11.99/month you get access to hundreds of Virtual Console games ala carte, and a selection of rotating NX software. You can purchase full blown NX titles as well for full retail price and they are streamed to your device. If you play a lot, you pay a little more in a year end server fee. Works on iPad, iPhone, AppleTV, PC, Mac, PS4, XB1, as well (you must have the Nintendo controller though).
