After seeing the Gamestop release schedule I asked Natsume if the list was accurate. And it is!
Natsume is releasing the Wii version of Harvest Moon: Magical Melody as a Gamestop exclusive title in the USA and Canada. After a good deal of consumer requests Natsume decided to publish the Wii-make since new Gamecube games are no longer available at retail.
We were told the Gamestop release date is pretty accurate so expect Harvest Moon: Magical Melody retrofitted with motion control in late August. However, it’s unclear if Natsume cleaned up the European release, which is missing the female protagonist and has Gamecube buttons left in the interface.
