I think Japan and Germany will be visited in TAR30. Japan was first visited in S9 and it was visited every three seasons after that (S12, S15, S18). However, it did jump one season early, but it did continue the pattern (S20 then S23 & S26). I think Japan will be visited one season later, aka S30. Also, TAR loves to go to europe, and its even better with the "winter theme", and Germany and Switzerland would be perfect for that, but I think Germany would be visited.
