No, Odama isn't coming to the Wii. At least, that's not likely. But on the final day of the Japan Media Arts Festival, the game's designer Yoot Saito took a little time to publicly tinker with the Wii Remote, showing how the Remote and Nunchuk could be used to replace or enhance existing control schemes by running through a quick game of Odama with them.
He was pretty impressed by the added immersion the Wii Remote could offer, as he says gesture controls can make games feel more realistic. Not that Odama is a game whose controls could have gotten any worse, mind you, but it's nice to see at least some devs tackling the subject of Wii Remote integration seriously.
