So, it's fun to speculate the upcoming route, and last season I correctly speculate three countries but it is more due to coincidence.
So, my speculation route is
1. Oceania. I have a strong feeling we'll start the first leg here. I speculate another Australia visit. It's been nine seasons since it is visited, and it's summer by the time they start filming, making it a perfect country. New Zealand and other Pacific countries can be visited too though, but Oceania should be visited since the last time we see it is in season 22.
2. Asia. Indonesia and South Korea are the ones to come in mind. When they shove us with three consecutive Indonesia combo, we all complained, but it suddenly goes quiet for five seasons, so could it be the time now? We haven't seen the infamous Lombok leg in American screen, and we know TAR USA sometimes recycles tasks from another version so it could be a possibility. Or they can use my Medan leg from TAR DC
South Korea will host a Winter Olympics soon, so it's a perfect time to visit before everything goes hectic. I can't think of another country.
3. Africa. We're lucky to get Africa for three consecutive seasons, but I don't want to test our luck by speculating it will be visited again. So, I guess no Africa this time, but they can surprise us. Making leg in Africa is not that expensive I guess.
4. Europe. Every even seasons, we always get a German-speaking country, so which country this time. My guess will be Austria. The last time they visit it is four seasons ago. Sometimes they also revisit countries that have been visited only once, so let's add Belgium to the pool. Scandinavia in winter will be wonderful, and we haven't seen Scandinavia since TAR 23, so there's a big probability we will see it soon. Since they have agenda to visit a new country each season, I have strong feeling we'll see new European countries, like Luxembourg or Slovakia.
5. South America. After being used for two seasons, I think it's time for South America to rest.
