I would go with safe bet and say 1 - 1.2 M
It could be more or less but we will see.
One thing I would say that bts Chinese scandal effected their individual sales a lot because most of the soloists with high album sales have a huge Chinese fandom support but for bts I think only v and jk's Chinese fandom are standing still now. I didn't see much Chinese sales for hobi and RM's albums. Idk about jimin. We will see
