For East Asia, we have the following in recent seasons already :
Hong Kong / Macau (30, 27)
South Korea (29)
China (28)
Japan (26, 31)
In the history of 31 seasons, only 3, 5, 7, 13, 22 and 25 have no East Asia visits.
I think the chance of 2 legs of India and then one leg of East Asia penultimate is high (like 20 and 27).
If so, most likely Taiwan or China will have it this time, probably in airport hubs like Taipei, Shanghai or Beijing.
