Nintendo doesn't do it because they don't have the teams to do what Ubisoft and Activision do. They also don't need to pump them out, so there's not a big reason to amp up the size of their teams.
Using the "Seal of Quality" is a joke as it gets slapped on anything published from Nintendo. I also don't get how you can really single out Call of Duty for its minimal changes when the very same can be argued. The real franchises where the argument can be made against annualized series are the sports games, but they're necessary with the need to have seasonal updates + contractual obligations.
