Lately, I have been getting into NCT more and I got myself thinking about some stuff 1. Is NCT 127 fixed? In Weekly Idol, Renjun mentioned that once you graduate Dream you can join the Seoul team. So are there going to be multiple groups based in Korea or will all the future units be in different countries ie. China, Japan, Vietnam, etc. 2. Will the foreign teams promote in Korea as well or just their given country? Like how JYP's Chinese boy group is only promoting in China. Because then they might not get many international fans if they only promote in a specific country. Look at Idol Producer, lots of international viewers lost interest overtime and in general not many people keep up with Chinese promotions. And something else I wanna add, but shifting members around does suck. One thing that really attaches me to groups is the group dynamic and chemistry among all the members. It sucks how you might really like the group dynamic, but it's only temporary for the rotational units.
