Zelda at launch was a strong boost...and I suspect they will get another boost at holiday season when Super Mario Odyssey comes out. But there are a lot of months in between that are not filled in with much...
Since the console is not likely to get any 3rd party AAA games Nintendo is going to have to court nearly every indie dev + churn out as many first party titles as possible.
Also I'm hoping for a $50 price drop after Christmas...
