Valkyria Chronicles 4 had already been announced previously (much to the shock of everyone, who expected the franchise to fall by the wayside, like so many beloved Sega IPs have). The western release was confirmed to be hitting the Xbox One and Switch in addition to the PS4, but unlike in Japan, we didn’t even have a release window to go by.
That changed today- Sega confirmed that Valkyria Chronicles 4 will be launching this Fall for Xbox One, PS4, and Nintendo Switch in the west. Simultaneously, Sega also launched the English official website for the game, which you can check out for yourself for some more information on it, should you wish to.
In Japan, Valkyria Chronicles 4 launches on March 22, exclusively for the PS4. A Nintendo Switch release is also planned, but it will be coming later, in the Summer. As you might expect, no Xbox One release is planned for the game in Japan.
