A Final Fantasy original! I'm interested.

This was discussed earlier, but I wanted to revisit the question about technology. Would technology be similar to FFXIII? XII? VII? If unfamiliar with those titles, will there be mechs and rifles for the imperial army or will the imperials focus more on swords, axes, bows, and maybe rudimentary rifles? 

For magic, will characters be using mana drive devices, born affinity to conjure magic, or perhaps a mix of both?
