Advanced solicitations for Shueisha's Weekly Shonen Jump's 30th issue are revealing that Future Trunks will be the newest Dragon Ball Z fighter added to Arc System Works' Dragon Ball FighterZ.
The jaw-dropping E3 trailer previously confirmed Goku, Vegeta, teen Gohan, Fat Buu, Cell and Frieza. With the game being 3vs3, we're guessing there's going to be a lot more DBZ fighters joining the fray.
Shonen Jump explicity states that the version of Future Trunks appearing will be from the Cell Saga of DBZ so don't expect him to have his Super Saiyan Anger form that he recently acquired in Dragon Ball Super.
