I do suspect Hyrule Warriors will influence Zelda WiiU in various ways, though. Didn't Aonuma say in an interview that he was inspired by the high caliber of cutscenes in Hyrule Warriors? If so, the Zelda team may step up the presentation in the WiiU game, which may extend to the music.The soundtrack in Hyrule Warriors comes from the developer (Omega Force), so there is little chance that Zelda U will be any similar.
Edit: Ah, yes he did - Aonuma determined for Zelda Wii U to have cutscenes on par with Hyrule Warriors
