They can even skip Southeast Asia because Taiwan has yet to have a cold-weather visit and its autumn is still milder than the rest of East Asia's.
I agree
Out of all Asia countries (The last visit season)
Japan (31)
South Korea (29)
Hong Kong (30)
Taiwan (19)
Cambodia (15)
India (27)
Malaysia (24)
Sri Lanka (24)
Singapore (25)
Laos (31)
Oman (17)
Bangladesh (21)
Due to the trend of revisiting the country in the recent seasons, I think Taiwan/Cambodia can have a real high possibility
Seconded, I'm expecting to see Taipei and Siem Reap along with Muscat.
I don't really know TAR will have a visit to some new countries
In East Asia, we have only 3 left (Myanmar,Timor-Leste, Brunei)
In Central/Souther Asia, we have a lot (Uzbekistan,Kyrgyzstan,Tajikistan,Turkmenistan,Maldives,Nepal,...)
In last season they made the first visit to Laos and Uganda so I think there should be 2-3 new countries in this season
Edit: I think Mongolia and Kazakhstan is way too overdue. Mongolia and Kazakhstan were visited 20 seasons ago. Can I see a Almaty/Ulan Bator/Vladivostok combo
