I just thought of something.
Since Xbox is the parent of both Rare and Obsidian, what if Obsidian made a new Perfect Dark?
I've heard great things about The Outer Worlds, which showed that Obsidian can make great first person combat, so if Obsidian was given access to Perfect Dark and applied some of what they did in The Outer Worlds it could be a great game.
But maybe that's just a pipe dream of mine, and I doubt anyone else here thinks it could happen. It was a nice thought though.
