regardless of the opponents, its great that Thai's of that quality are going to fight in the states. America are up there with the best in most sports and martial arts, but they are lagging behind in Muay Thai. They can normally do everything 'in house' and have enough knowledge and talent to take them to the top in practically every other area, but have never really looked outside of america for thai boxing with the exception of toddy and chai and its been to their detriment as their top level thai boxers are no where near the calibre of the UK and other countries.
i imagine this will begin to change though as real muay thai starts to filter through there properly and having fighters like Buakaw and Saenchai there can only be a very good thing for them.
i would think that paydays in the USA are pretty good too so i hope that more English fighters also get some promotion and opportunities there too!
