It started out a relatively under-appreciated (but brilliant) PS3 turn-based war game. Then the sequel founds its home on PSP, and it seems to like it there because the third game's also on its way to the portable and below is the first trailer.
Having come straight out of the Tokyo Game Show, it's all in Japanese so you might not know what's being said, but it's pretty and all that.
Valkyria Chronicles is a cel-shaded, anime-style turn-based strategy war game with a battle system that somewhat resembles Advance Wars. Players take turns to move units within reach of their mobility range, fire on targets and move into cover before passing play to their opponent.
The game's expected for release in Japan on January 27, 2011 in Japan. No western announcement has been made.
