Sorry if I didn't follow you, but "the" disk I said above means the one you already have as long as you purchase the physical copy of Cyberpunk 2077. When you upgrade to the next gen, you're only required to have the next console with "disk drive" for verification process as such. So for example: you purchase PS5 standard version and CP2077 PS4 version on physical copy , then (when the time comes) you have to insert PS4 disk into PS5 for verification (that means "you own CP2077!"). After that, upgrade process to PS5 version will commence; that's what I understand.
We don't know (yet) which languages are available on console version of CP2077, but considering TW3 I wouldn't expect NA region supports Korean (you should see
here). If I were you, I'd set my hope on
PlayAsia not Amazon US. Sorry that I wasn't helpful much, but Good luck! (FYI: the physical copy on Xbox won't be available in Japan neither
)
P.S.
Congrats on Korean dub announced
