Letter From the Producer IX.

OMG

Chill

The question was, why would you implement the content first if it's supposed to be used with the new battle plans that aren't implemented

Because they're releasing them at the same time.

My method of response has nothing to do with our argument.

1.18 is going to be relatively bigger than previous patches. This means that balancing is going to take more time than usual, and so we’re anticipating a somewhat longer period between patches. Even if we break off some of the content and release it ahead of time in a 1.17b patch (which me might!), 1.18 will still go live sometime in mid-June at the earliest. Sorry for that.

He says they might use 1.17b for some of the content. That could mean anything from battle system changes to more sidequests. It doesn't mention anything about the dungeons specifically. I'm sure they wouldn't release dungeons specifically designed for the new battle system before they actually implement the system.
