You can expect information on Bravely Second, the sequel to Bravely Default, this Summer, according to the official Bravely Default Twitter account. (Thanks, GoNintendo)
Yesterday, a Twitter user asked the account—which is normally run by Bravely producer Tomoya Asano—whether the game would be at E3. To this, the account replied (in English): “I’m sorry. Already wait a minute. m_ _m”
Shortly thereafter, the account tweeted (once again in English): “Wait for the information of the BRAVELY SECOND until summer.”
For now, we interpret this to mean that more information on Bravely Second will be revealed in Japan this Summer—not that the Twitter account is confirming a western release. Of course, seeing Bravely Second in the West wouldn’t come as a surprise at all, given how well Bravely Default did.
