Natsume have touched upon their E3 plans in a post to their Facebook page. The publisher’s community manager said the following, with regard to E3 plans:
We know our fans are anxious to hear what we’ll be showing, and we’ll have lots of news coming over the next two months as we get ever-closer to the show’s launch. While we can’t discuss any specific titles at this time, rest assured that many of the staple Natsume series that we’re known for will be in attendance. We’ll have a final line-up of games that will be showing during E3 (June 10th-12th) in late May or early June!
Natsume are known for publishing the Harvest Moon games in North America. In Japan, Marvelous recently released Harvest Moon: Connect to a New Land, so perhaps we’ll hear Natsume talk about their plans for the game at E3.
