Falcom has just surveyed the community on Twitter to see if we would be interested in a possible PlayStation 4 versions of Trails of Cold Steel I and II. The studio, always listening to the players, organized this survey following the request of a fan and it would seem that the first returns are more than favorable.
It would not be at all surprising that the developers prepare us a PlayStation 4 version for the first two parts, originally released on PlayStation 3 and PlayStation Vita.
Also remember that The Legend of Heroes: Trails of Cold Steel III is currently in development on PlayStation 4 and will be released in late September in Japan. An improved PC version is already available for the first part, so it would be a perfect opportunity for players to take everything on the latest Sony console.
