So, those teases of a new Saints Row project have now been revealed - one is a new standalone expansion called Saints Row: Gat out of Hell, featuring Johnny Gat and Kenzie venturing into hell, which you can see the trailer for here. And the other is Saints Row IV: Re-Elected, a current gen remastering of the game for PS4 and Xbox One.
The game will come with a graphical upgrade, and includes all prior-released DLC and content. So if you skipped Saints Row IV on last gen or PC, this could be worth picking up.
Saints Row: Re-Elected is due for release in the US on 27th January, 2015, and 30th January in the UK, for PS4 and Xbox One. It will cost $29.99 on it's own, or $49.99 if you buy it bundled with Saints Row: Gat out of Hell. Thanks, Polygon.
