Following the trademark filed by Sega Games in Japan for "Aoki Kakumei no Valkyria" (translated by a couple of outlets as "Valkyria of the Blue Revolution"), on November 3rd they added a trademark for an apparent english translation: Valkyria: Azure Revolution.
While presently nothing is known beyond the name, it seems fairly certain that Sega intends to bring the title westward, or at least outside the Japanese isles.
