It is looking increasingly like the Chang International Circuit in Buriram, Thailand will be added to the MotoGP calendar for the 2018 season. (I understand from sources that there was a significant hurdle to be overcome: circuit title sponsor Chang is a major beer brand in Thailand, and a rival to the Official MotoGP Beer Singha, also a major beer brand in Thailand and further abroad. The race can only happen if a compromise has been found to accommodate this conflict.)
This is good news for Thailand, and good news for fans in Asia. The World Superbike round at the circuit is always packed, and MotoGP should be even more popular. It is hard to overstate just how massive MotoGP is in that part of the world. From India, through Southeast Asia, motorcycle racing in general and MotoGP in particular has a huge following. But the only country in the region which has a race is Malaysia, hosting its Grand Prix at Sepang.
So expanding the calendar to include Thailand is a welcome addition for fans in the region. If the financial and logistical problems with organizing a race in Indonesia ever get sorted, then there might even be a third race in the region, at the Palembang circuit in South Sumatra. Given the massive interest in MotoGP from that country, it is a racing certainty that any race there will be a complete sell out.
