The latest issue of the Japanese magazine V Jump has a page dedicated to Final Fantasy XV. If you pore over the scan, you can see Noctis squaring off with what looks like a giant titan creature, and the bros driving the car straight through a city (harking back to the days of FFVIII even more). But, chief among them, is what appears to be a female mechanic with blonde hair, goggles around her neck, the appropriate mechanics' attire, sans the obligatory cleavage at full view.
Fans of the series will associate mechanics and engineers first and foremost as Cids. We've had borderline-insane Dr. Cid, a young brigadier general Cid, and an Adolf Hitler Cid, but there's never been a female Cid. The scan however, does not refer to her as Cid, nor is she given a name. So for now, her identity is still out with the jury.
