Nintendo didn't need Third Parties to sell the Wii, they did that all by themselves.
the Wii sold so well because it was something completely different and new, and it appealed to people who arent even into gaming. it was both a game console and a toy that could be enjoyed by pretty much everyone. however, the gimmick of motion controls has worn off by now. Sony and Microsoft abandoned the idea pretty quickly, and Nintendo has as well.
Nintendo needs to ensure that their next console can compete with the others in terms of power and online experience, and they also need some more mature exclusives and new IPs. unfortunately, i dont see any of that happening, and i wouldnt be surprised if they ended up going the way of Sega and stop developing home consoles altogether.
as it stands, Nintendo is relying solely on nostalgia. the only thing that made me buy a Wii was Mario Kart and SSBB, with the hopes that there would be other exclusives that interested me, but there never were any. i learned me lesson and wont be buying a Wii U, even though i really want to play Mario Kart 8. basically, there is little reason to buy a Wii U unless you are a fan of every series they have been offering for decades. you need to be a fan of Super Mario, Mario Kart, Mario Party, Donkey Kong, Zelda, Star Fox, and Super Smash Bros. because that is basically all they have to offer.
they really do need third party support, and they wont get it until their consoles are closer to being equal to Playstation and Xbox.
