A new screenshot of Lightning has been released in all it's HD goodness. The image has previously appeared in both Dengeki and Famitsu scans from after Jump Festa. The interview that the image came from is about Square-Enix's recent adoption of the Unreal 3 Engine for use in other games and it's mentioned that it will in turn "advance the development of FFXIII". Thanks to GHenrik for finding it.

EDIT: Any mention of FFXIII has been removed from the original interview. The Unreal Engine was apparently going to help "advance the development of FFXIII" (assuming it would take pressure off people on the team working on other games) but some sites have said it was going to replace the White Engine and be used for FFXIII. This is untrue and the White Engine is still being used to develop FFXIII and Versus.
