It looks like Bandai Namco is laying some groundwork for a few new titles as it has been uncovered by Hokanko that the company has filed a number of new trademarks in Japan. While a few of them aren’t all that interesting for the moment, such as Baloon Bash and Brave Scramble, one of these trademarks does hint towards a future Tales game.
A trademark has been filed for Tales of the Best which may be some type of collection or crossover game featuring characters from various Tales titles. Of course at the moment this is simply speculation since it could very well be a simple smartphone game as well.
