Nintendo's strategy has worked well for them in the past. While the inclusion of third-parties can certainly help them, if they were so inclined, it's not really necessary if they manage their business properly.
Nintendo's problem is that they haven't been managing themselves properly, and without third-parties to pick up the slack, it's been rough for them.
Honestly, I think their problem is they've been going through a rough transition. Unlike Microsoft and Sony, they're still very much a toy company at heart, and I think that the change has percolated down to development, but hasn't quite managed to work its way up to management yet.
I believe in honesty, civility, generosity, practicality, and impartiality.
