Well for one thing, they could become EA and buy all third parties. But they didnt do that, they relies more on 2nd and 1st party titles instead. And since the Wii had launched, do they even need to? WSR, Wii Fit and Wii Sports alone can take the Wii a long way and make Nintendo profitable. Most third party games are just fillers in flood of all wii games out there. Its the Nintendo published titles that makes profit on the system anyway... Just seacrh the sute of million sellers on the wii. Most of them are Nintendo published games...
