It depends really on if Kpop continues as a pop culture phenomenon or not. I love BTS and their story is unique but I don't see why another Asian boy or girl group couldn't achieve more.
If Kpop stays as it is (and subsequently grows) I see it happening. But I don't think it will happen with any boy or girl group in this generation. Maybe if a company gets the right Korean-American soloist but not a idol type.
If Kpop goes the way of Jpop then the whole Hallyuwave will end and it will go to another Asian country (China further down the century?) and their group, more then likely inspired off of Kpop, will do it.
