i remember someone saying that birth by sleep volume two takes place during between kingdom hearts and birth by sleep, and that it should be about aqua, riku and king mickey so that way nomura's stories of "riku and king mickey's absences" will be revealed along with aqua's new story of "aqua's absence"
also i think volume two may reveal connections to the next saga after the xehanort saga by clearing up the last hidden details of the xehanort saga before the final battle in kingdom hearts III and possibly may reveal a new antagonist for the next saga, possibly the primary antagonist that the next saga could possibly be named after.
