B button could be used for final blows or something new like an area-attack and hefty attacks. Parrying with triangle happened only in special occasions, otherwise you had to dodge roll, parry, take the damage or be swift and attack first. Not forgetting the magic, it should be mapped on the D-pad. Maybe dodge rolling could be done with nunchuck+some button+c-stick or just c-stick+some button. Otherwise if they don´t use any Wiimote features, they should just make it for Xbox360/PS3 although they would lose most of the young demographic.
Also I preferred KHII over KH and enjoyed the fast pacing much more, the battles were really more enjoyable than before. So if that´s not possible on the Wii to use the Wiimote features, one more reason to go the PS3/Xbox360 way.
And it still possible to develop at lower costs for HD consoles and that´s if you use PCs as developing tools. Your graphics and other technical stuff don´t need to be top-notch btw.
