Valkyria Chronicles was released exclusively for the Playstation 3 on November 4, 2008. At that time, trophy support wasn’t a requirement for a Playstation 3 game. Even so, the possibility is there for Sega to patch trophies into the game.
However, they will need feedback from fans before deciding to do so. Aaron Webber, the Assistant Community Manager for Sega of America, posted the following comments on the Playstation.Blog:
“If you do want to see trophies (and I know that’s a lot of you here), then please do keep an eye out. I’d like to organize all of your feedback together so I can show some people here at SEGA just how many fans out there want them. Numbers speak loudest!”
