Natsume plans on releasing five Harvest Moon games this year including Harvest Moon: Sugartown which was shown in their E3 booklet with a Q4 2009 release window.
Marvelous released this game in Japan this past March. Usually, Harvest Moon titles take more than nine months to crossover.
In Harvest Moon: Sugartown players grow crops, care for cows, and take part time jobs to save the village from a corporation trying to replace their home with an amusement park. Harvest Moon: Sugartown has multiple endings, but I doubt one of them will have the corporation taking over and cows running the roller coaster ride.
