If they add another upgradeable weapon like relic, since they love to gate everything, I wouldn't be surprised if you have to have the finished zodiac relic to start on the "new" one.
If they do that, expect them to tone down the quest. Just like 1.0 Relic -> 2.0 Relic.
Wouldn't be surprised if they toned down some of the steps immensely for 2.4 since they said that it was on the table when the ilvl goes up.
