This one was already announced at the Marvelous showcase a few weeks ago. It's... for people who aren't aware, Marvelous is the company that owns THE OG farming series Story of Seasons(Harvest Moon) and Rune Factory, so this is a third farming franchise they're trying to get off the ground all of a sudden? Given what we've seen it looks like this one is maybe completely omitting the life sim elements which i guess is why it isn't just Rune Factory 6 (which, they also announced another one of those a few weeks ago).
It's fascinating to see the company who maybe has the most total farming games in simultaneous production still going for more. Really goes to show how much people seem to feel like the genre's audience has expanded lately, imo
