In a new interview with Famitsu magazine, Bravely Second producer Tomoya Asano has already begun the planning stages of the third installment in the series:
You might say “what” at the timing [of this annoucement] but there is already a concept for Bravely Third inside my head. If sales for this title [Bravely Second] are good, then I plan on submitting a proposal immediately. Please give me your support.
Hopefully Bravely Second sells well enough to warrant those ideas in Asano’s mind.
