Just as a notice, Nintendo has worked on several partnerships this gen with third parties (I'm referring to titles like Bayonetta 2, Hyrule Warriors, Lego City Undercover, #FE - and such parternships are what I'm eager to see come back next gen, maybe even more numerous). Morevoer, they recently completely revamped their developers' portal (now it's modern + it hints at much better comunication for in-development projects), they're keeping on improving their relationships with indie developers, and they're (seemingly) a Khronos' contributor, the second highest role in terms of relevance. Plus, we shouldn't forget the support 3DS gets from Japanese third parties (even if it's down compared to the recent past...but it's what happens when your console is nearing 5 years since its launch AND doesn't allow multi-platform releases that are cheap to develop, like Vita).
So, yeah, while there have been several hints about Nintendo trying to catch a bigger audience again, it doesn't seem like they're ignoring the more traditional audience. Actually, some of what I've listed signify an improvement compared to what Nintendo was used to do.
