Think a okami sequel would be perfect for the new Nintendo HD system coming in the future, judging by the rumours there's a touch screen controller (for the celestial brush)with some pretty powerful graphics to make a game beautiful on PS2, wii and DS even more beautiful
But this is just me hoping because I'm getting the console because I'm a nintendo nut

It would probably be good with playstation move and kinect too, but I reckon if the rumours are true the new nintendo system would be best considering the brilliance of okamiden's touch controls
