Siam got their game guide today, confirming Doi Suthep is their associated wonder... But the major news was that with the last Dev Diary we saw the full list of leaders in vanilla in alphabetical order, being those 19 with 2 leaders still not revealed, if you count Napoleon (free DLC) and Tecumseh (pre-order bonus/paid DLC) the total number at launch is 21 leaders. As said, the list is in alphabetical order, and the missing leaders are between Confucious to Harriet Tubman and Isabella to Lafayette, that gives a ton of weight to that Friedrich (the Great) mention by the ESRB rating... So some edidts, besides Kamehameha and Kublai Khan the other people mentioned that could be leaders do not fit the possible slots so they are on possible near DLC category now, also Siam description mentions Lanna, Laos and Malaya so these are going there too.
