My ideas.
I'd like to see some 1st person perspective boss battles (think Mystical Ninja starring Goemon on N64...also developed by Konami). The physical throwing motion could be used for whip, boomerang, holy water, ax, etc...while the nun-chuck could allow for movement and dodging (motion). That's just for boss battles, not full game.
Another direction I suspect it could go in is 3D action but I think the IR will have a more profound use than the motion gestures though it will be used as well.
Picture a 3rd person action game like Heavenly Sword but in a Castlevania setting. The IR points where the whip attacks and gesture motions create wide arching attacks or a full overhead 360 degree swing.
IR pointing at special tree branches, rings, etc... allow the whip to attach and swing across like in previous titles.
Other gesture motions solve puzzles, open doors, operate other weapons like the boomerang, holy water or ax.
The rEVOLution is not being televised
