Thailand, Australia - not very surprised
Korea - Hara and Niels joined KMRCA there, this is the main point!
Japan - If it's this country, there should have a bunch rumour already, but nothing still happened. OFF Road Worlds held there this year, should not held another in short time !
China, Taiwan - almost of all drivers are from GP, there is no interests.
Singapore, Hong Kong - I don't think they are prepared for this, small cities, Hong Kong has give up to organize bigs RC events long time ago, nor Singapore have so much experience, instead of 1/12 World held in long time ago.
Indonesia, Malaysia, Phillipines, N. Zealand - they have tracks for this but never held any big events before, little chances.
