Rune Factory 4will start up a European production line thanks to Zen United, the same distributor that handled the continental carriage of Harvest Moon: A New Beginning and Persona 4 Arena. Zen director Geraint Evans didn't disclose any details in an interview with JPGames.de, but an official announcement in the "very near future" may produce more info.
As for North America, the 3DS agricultural sim/RPG is due sometime this fall. In August publisher XSeed said it "could be looking at a late September or October release," although late September is nearly upon us and a release date hasn't cropped up yet.
