Highly speculate the following countries will be visited for TAR 28
Asia :
South Korea : China & Japan are visited recently (24,26,27), South Korea fits the best for a "Eastern Asia" spot
Cambodia : Bangladesh, Vietnam and Thailand are visited not too far ago (21, 22, 26), it fits the best for "poor Southern Asia" spot
Indonesia : Philippines, Malaysia and Singapore are visited recently (24,25) leaving Indonesia to fit the "Island Asia" spot
Indonesia also makes easier connection to Oceania
Oceania :
Australia : Last visited was 18 already, possibly 2 legs, visited mid-race (Leg 4-6) with 7-8 teams
Fiji : Continue the trend of one new country since 25, also adds variety to Oceania
Europe :
Russia : The last Winter visit to Russia is 14, making it possible
Belgium : France, UK, Spain, Portugal, Germany, Netherlands are all heavily featured in recent races, a Winter visit to Belgium makes things less predictable
Lithuania/ Czech Republic/ Croatia/ Finland : Possible candidates for Former USSR countries, all are formerly visited in Summer only
Africa and South America will be skipped likely given how frequent they are featured in recent races
A Westward route is suggested (Leg 1-3 : Asia, Leg 4-6 Oceania, Leg 7 Asia, Leg 8 - 11 Europe)
