Here is an E3 preview via RPGamer.
Very nice. Here is my favorite part:
"The wonderful thing about Valkyria Chronicles is how it delivered the immense joy of masterminding a tactical sweep across a map, taking out enemies one by one and advancing my position, and then capped it off with the satisfaction of lining up a headshot. Oh, and it also let me run over enemy units with a tank."
Yay!
