The Russian retailer called Game Buy has recently added to list Batman The Telltale Series and Guardians of the Galaxy The Telltale Series versions for Nintendo Switch, never officially announced by the publisher.
If we take into account the information filtered by European retailers, it is possible that in the future we will see Batman: The Telltale Series on Nintendo Switch. The first retailer that talked about this was the Russian online store Game Buy, which has this version of the game in its catalog, along with Guardians of the Galaxy: The Telltale Series as well. However, this deal is not very well known outside that nation. But luckily, other companies have corroborated this information.
In both cases, the stated release date is June 30, which definitely looks to be a placeholder in a way it is represented. In the past, Telltale Games has brought its flagship series on almost all platforms on the market, also the company has already confirmed the arrival of Minecraft Story Mode on Nintendo Switch, so it is not excluded that Batman and Guardians of the Galaxy can actually make their appearance on the new Nintendo console.
At least two UK stores, ozgameshop and 365games, also have Batman: The Telltale Series among their catalog of future releases. However, those who have the last word about the release of this adventure are of course Warner Bros. Interactive Entertainment and Teltalle Games. We will have to wait for some of them to confirm this news.
