One of the more inexplicable quotes to emerge from this year's E3 event was Reggie Fils-Aime's warning that "pirate arrows are going to come at you from all directions and find their mark," -- an unlikely utterance that's right up there with "giant enemy crab," as far as I'm concerned.

When the subject of Fils-Aime's odd choice of words was demonstrated in greater detail at the end of the conference, however, Nintendo strongly hinted at the development of a new Rhythm Heaven game for the upcoming Wii U console.

In the "Shield Pose" demo, players block suction cup-tipped arrows by moving the Wii U's tablet controller. Gameplay is synced to energetic music, and each successful block earns players encouragement from a bubbly female voice -- all hallmarks of a Rhythm Heaven minigame. Fils-Aime notes that current Wii U concepts are not guaranteed to blossom into full games, but it's difficult to believe that the new hardware's capabilities wouldn't be showcased in a future Rhythm Heaven release...or, at the very least, another WarioWare sequel.

Nintendo is also showing off a Wii edition of Rhythm Heaven at this year's E3, though neither a title nor a release date for the sequel has been announced.
