You're referring to the upcoming DLC (Downloadable Content) for the popular video game series, Portal!
As of now, there hasn't been an official announcement from Valve Corporation, the developers of the Portal series, regarding a new DLC. However, there have been rumors and speculations among fans and gaming communities about a potential new installment or DLC.
In 2020, Valve Corporation released a free update for Portal Knights, a spin-off game in the Portal series, which added new content, including new levels, characters, and game modes. While this update wasn't a full-fledged DLC, it did hint at the possibility of more content being developed for the series.
It's worth noting that Valve Corporation has been busy with other projects, such as Half-Life: Alyx, Half-Life: Opposing Force, and Counter-Strike: Global Offensive, so it's possible that they might be focusing on those projects before returning to the Portal series.
If you're eager to get your hands on new Portal content, I recommend keeping an eye on gaming news and Valve Corporation's official social media channels for any updates or announcements.
