Hell, maybe it's Blood Dragon 2, which would also be just as nice to see. According to VG247, this isn't the first mention of a new Far Cry game being in development.
This isn’t the first time we heard some Far Cry 4 whispers through grapevine either. Last October composer Cliff Martinez said he was working on the game, and Ubisoft has always been keen on the idea of a sequel to Far Cry 3.
But really, is this at all surprising to anybody?
