GameFly just put up the listing for the game which was announced by Aksys and Toybox (formed by the creator of Harvest Moon/Story of Seasons) for Switch and PS4. As you can see from the last screen above, it's the Switch version shown. The page has a date also for August 24th in NA at least.
Looks really nice! Might be the Harvest Moon: A Wonderful Life successor that's been long overdue! :P
