Nintendo is in the vastly better position. Things like Pokemon, Mario, Animal Crossing- sort of gurantee a safety net of many millions of adopters, particularly with their handhelds.
Xbox relies heavily on third party support. They would be completely screwed if Sony moneyhatted exclusives for some big titles.
also something interesting to keep in mind is that DESPITE Nintendo releasing a partial new portable hybrid (the Switch), there last handheld, the 3DS, still is selling somewhat competively with the X-One.
that suggests that there is certainly more of a demand for Nintendo hardware than the Xbox brand at this poiint of time. And I think branding is probably where the Xbox division is the weakest- what do you really think about when you think of Xbox? Halo? Gears? there aren't enough big franchises and IP to have pushed the division to a huge connection with consumers worldwide.
