Just saw the news that the Do As Infinity best album was also postponed, from the previous March 10 to March 24, 2021 for the same reason (production problems).
Seeing that there are other avex talents who have also experienced this, it seems that there is a problem in the production process. So I wouldn't have too much hope for re-recordings or new arrangements.
