Give the Harry Potter team at EA some credit: They take advantage of emerging technology to keep their games from being completely formulaic. First it was the EyeToy support in the PS2 version of Azkaban, now it's wielding the Wii remote like a wand in Harry Potter and the Order of the Phoenix, due in June. Since you also use the nunchuk, does this mean Harry is actually part-ninja? Perhaps that's the secret J.K. Rowling has been holding back...
