So far all of the DLC has been related to the next game. Horizon 1's Rally Expansion brought off roading to the series which was the main showpiece of Horizon 2. Then Horizon 2's Storm Island brought extreme terrain and variable surfaces which is one of the main selling points of Horizon 3 and now we have Blizzard Mountain, which has a mountain. Japan has mountains, a lot of them and some have snow on them. My logic is irrefutable.
