Mine:
-BLACKPINK new album (if they drop one this year) is 100% surpassing 2M sales.
-At least one NCT unit album will be able to surpass 3M copies with a single album.
-SEVENTEEN full album can possibly surpass 3M but my final bet is close enough.
-SKZ And ENHYPEN sales are crazy insanely so they can possibly surpass 2M copies.
-TXT will 100% have an album with 1M copies this year.
-BTS new album will sell over 5M copies.
-TWICE will have their first million seller album.
-Ateez is also showing signs to surpass 1M copies with an album in 2022.
-The Boyz will be near million seller, with more fandom growth they can possibly surpass the 1M Mark.
-I really can see AESPA having an album with over 750k copies this year.
