I would guess that weekly currency for craft/gather would be subject to the same delays for the same reasons, so you don't feel rushed to reach lv60 and start capping currency in the very first week.

But yes there's no official words on that specifically right now. Sounds like you are aware of the 2wk and 4wk staggered rollout for battle content and currencies. I believe that is still the most recent information we have. Can only guess how it relates to craft/gather but I'm sure all will be made clear before launch.
