It seems a new entry in the Naruto Ultimate Ninja Storm series could be on the way. Bandai Namco filed a trademark for what could be a new game. The European Union Intellectual Property Office featured a trademark for Ultimate Ninja Storm Connection. As expected, the filing applies to things related to video games like software. [Thanks, Gematsu!]
The Naruto Ultimate Ninja Storm series is a part of the Naruto Ultimate Ninja/Narutimate fighting game line from CyberConnect2. This line kicked off in 2008 for the PS3, before also appearing on the PS4, Switch, Xbox One, and PC with the Ultimate Ninja Storm Trilogy that included the first three entries. The most recent release was Naruto Shippuden: Ultimate Ninja Storm 4. That started out on the PS4, Xbox One, and PC in 2016. However, in 2020 a Switch port appeared.
Bandai Namco didn’t officially announced anything related to Ultimate Ninja Storm Connection yet. Its current active Naruto fighting game is Naruto to Boruto: Shinobi Striker. Despite coming out in 2018, it still got new DLC through 2022. There are also regular Ninja World League updates in-game. Some “after” Fall 2022 updates for it will include more stage renovations and ninjutsi rebalancing.
