Reddit user ThemeParkFan2020 discovered an unusual and possibly suspicious change to Ubisoft's official Rabbids Twitter account handle, leading some to speculate that an announcement for a possible sequel to Mario + Rabbids: Kingdom Battle may be imminent. Previously @RabbidsOfficial, the username has been updated as @MarioRabbids. This change is particularly interesting considering it happening so suddenly, almost 4 years after the release of the original crossover. Due to the success of the original, it doesn't seem too unlikely that a successor could be in development. We'll just have to wait and see!
