Norway and New Zealand are already in the game as Oceania and Scandia. United States could be something coming to the real WRC in 26 at the earliest with an event in Chattanooga Tennessee running demos and test events currently. There's a Welsh event in ERC next year so keep an eye on that coming back in the future. Assuming they keep updating the game as they did both could be official events down the road. Also the Central European Rally in the game is an event co-hosted by Austria, Czech Republic and Germany so that kinda covers 2 of those as well.
