V-Jump Magazine in Japan has revealed the name of the 'Silver-Haired Character' from the E3 trailer for FFXIII, as well as some details on his background.
Additionally, the magazine provided some details on the 'Gestalt' (or vehicle) mode of Odin's summon, including its form and the controls for it. You can likely expect some better images to show up on the official FFXIII site in the near future.
