If you want to wait patiently, we will get Story Of Seasons (maybe) later on this year. Though it has no Harvest Moon title, it's the recent Bokujou Monogatari, the first published by Xseed since they got the license to port. Harvest Moon is still Natsume's IP, and they are going to publish their own Harvest Moon game (The Lost Valley), which is not a Bokujou Monogatari title.
