Asobo working on a new Project with MS. https://www.madinfinite.com/news/2020/09/asobo-studio-says-it-will-maintain-content-support-and-updates-on-microsoft-flight-simulator-for-10-years/
So they are working on two things right now, one being a project with Focus Home Interactive which is possibly Plauge Tale 2 and another with MS which is hopefully a traditional game like Plague.
MS might be buying them in the future imo but not now, unless they did already buy them and the team has to honor the contract with Focus Home like Obsidian with Private Division.
