Even though NCT concept is unlimited amount of subunits and localized groups across the world; for China and Japan and SEA countries; kpop is already popular there and familiar to them so launching a group in these countries under kpop system is easier. However kpop is seen as foreign in the US. Why can't SM launch a regular Western boy group without linking it to kpop that will turn away locals? A Western boygroup with kpop style choreo and fan interactions.
Also the Smtown instagram post that announced it seems to mention only one will be chosen in the reality show. So the rest will be other NCT members or new trainees? All this big reality show for a boygroup and choosing only one winner doesn't make sense.
smtown statement- Two entertainment pioneers are teaming up to find the next K-Pop star in America!
Not to mention SM music is so unconventional even for kpoppers how well it will be received in the West?
