Gah! Final thoughts and predictions:
Eastern Asia:
Probability: Definite
China
Probability: Likely
Although I wouldn't be surprised if it got featured, I personally don't get a "WE'RE GOING TO CHINA AGAIN THIS SEASON!" vibe. There isn't much to base this off of, just a gut feeling- a hunch, if you will.
Eastern/Northern Asia
Probability: Likely
South Korea, despite the ever present 'threat' posed by their Northern neighbors, would rank high on my list from this general area. Japan, is very possible too. Would love to see Eastern Russia (Irkutsk, Lake Bikal, Vladivostok, etc.) featured, or a return to Mongolia, but my bet is that they're not in the cards for this season.
South East Asia
Probability: Duh!
With the general pattern that there is, I would not be surprised if there was yet another Thailand *cough cough* Bangkok *cough* visit (Hopefully this time with Laos)... Is Myanmar ready for a visit yet? I would start to lean towards no, personally... Malaysia/Singapore haven't been visited in a while, nor has Hong Kong/Macau. Taiwan doesn't seem likely as of yet (visited in S19). NO. INDONESIA. KTHNXBAI. And finally, the Philippines- Brunei and East Timor will def not get a leg, Cambodia doesn't seem exciting enough comparatively- I believe that the Philippines will definitely get a visit somewhere in the next three seasons (whether it's this one or not, we will soon find out).
South Pacific
Probability: Unlikely
Only country I can really see is Australia- Melbourne and Tasmania, to be exact. Papua New Guinea may have a really outside chance, but with 3 legs in Oceania last season (two of which were on tropical, Polynesian Islands), I really can't see much else from here being featured quite this season.
