Let Banjo & Kazooie aren't owned by Nintendo. They were owned by Rare, who were purchased by Microsoft. So they couldn't but Banjo & Kazooie in the game unless they have permission. That, or they wanted to give the Duck Hunt Dog more love, since everyone who's played Duck Hunt hated that little bastard.
