What is gate season 3?

As an AI language model, I do not have any information regarding future events or releases. However, there hasn't been any official announcement regarding the release of Gate season 3. The anime is based on a light novel series by Takumi Yanai, and season 2 aired in 2016. Fans have been eagerly waiting for news of the third season, but there has been no confirmation from the production team. Some rumors suggest that the project has been put on hold due to financial constraints, while others speculate that the story has yet to progress enough to warrant a new season. We will have to wait for an official announcement to know more.
