Update - Sat 22nd Feb, 2020 00:21 GMT: It looks like the polish-developed RTS Ancestors Legacy really might be released on the Switch. According to GoNintendo, Amazon's US website has now added a listing for a Nintendo version and so has the retailer Deep Discount.
Both listings mention a release date of 19th May 2020 (just like Japanese listing). There's also a description referencing network support for 2-6 players and the game requiring a 13GB minimum save size. If these listings are accurate, keep an eye out for a more official announcement in the near future.
Original article - Sun 2nd Feb, 2020 15:00 GMT: It's almost a weekly tradition now for Switch titles that we haven't officially heard about to pop up online. A lot of the time, these listings end up being confirmed months later. Games like The Witcher 3: Wild Hunt for Switch were partially discovered this way, and more recently Metro Redux was finally revealed after multiple store listings and a PEGI rating.
Now, in the latest news, there's a listing for a Nintendo Switch version of the Polish squad-based real-time strategy game Ancestors Legacy on Amazon Japan. It goes on to mention a 19th May 2020 release date (thanks, @JPSWITCHMANIA):
This title was developed by Destructive Creations and published by Russia's 1C Company. It was first released on the PC in 2018 and was then ported across to the Xbox One and PlayStation 4 in 2019.
The Steam version has "very positive" reviews and the game itself is inspired by medieval European history in the Middle Ages – bringing together the stories of four different nations (Viking, Anglo-Saxon, German, Slav) and their conflicts. Your job is to conquer, raid and pillage camps, villages, and towns, while managing temporary bases and settlements, and utilising the "full range" of tactical available options to take strategic advantage of the environments.
