Frankly, at this point all I'm looking for from Nintendo are its classic IPs. I'd love to see some new first-party characters and concepts to go alongside DK, Mario, etc., but I've come to accept that no Nintendo platform will ever again offer a broad, robust library that covers the entire spectrum of gaming. I mean, that hasn't really happened since the Super NES over two decades ago, so it's pretty pointless for us to keep pushing them in that direction. Nintendo has lost more third-party support with each successive console (well, not counting the Wii party games), and they've proven time and time again that they either have no interest, or are incapable, of ever getting it back.
At this point I think Nintendo would be better off positioning themselves as more of a boutique brand, like the PIxar of video games. As with Nintendo games, most people wouldn't buy just Pixar movies, but they have a great reputation, do big business, and nobody ever complains that Pixar doesn't do hardcore action movies, rom-coms, or anything but what they do best.
Nintendo is what it is, and its execs should embrace and glorify what it does well and quit pretending that its systems can still compete in every area. When Reggie or whoever tries to convince people that Nintendo platforms are good choices for sports games, first-person shooters, etc., it just makes them look like clueless losers.
