It's fairly simple. SOME gamers want the Nintendo exclusives. MOST gamers want the big blockbuster third party titles. Nintendo only needs to figure out if they want SOME gamers or MOST gamers and plan their actions accordingly.
The point is, they are relying too heavily on their own titles. Those titles are not to everyone's liking, no matter how good the quality. That will only get them a certain dedicated crowd, which will be dwindling away more and more each generation. You need a good combo of first and third in order to make it big. The stars need to be somewhat aligned as well, but that goes for everyone.
