Rumour: It seems the next LEGO game is another LEGO Batman game
The LEGO Group and TT Games launched LEGO Star Wars: The Skywalker Saga last year and the game proved to be a sales success as it had the biggest launch of a LEGO video game ever. TT Games is currently working hard on their next project which appears to be another entry in the long-running LEGO Batman series of games. The news of the project leaked in a comment left on Fanbyte by one of the game's staff and was discovered by an ex-employee.
The team at TT Games had been working on LEGO Disney but the project was scrapped last year in favour of the more lucrative Disney Dreamlight Valley
