It seems we now have a release date for Marvel’s Guardians of the Galaxy: The Telltale series, and it’s only few months from now. You can pre-order the game from Gamestop already and they have a release date: April 25th 2017!
The game will feature a new side story that will blend in with the upcoming Guardians of the Galaxy vol 2 movie. As is custom to Telltale Games, the game will be five part episodic series and your decisions and actions will determine the path of the story you experience.
Keep in mind two things: Telltale hasn’t confirmed this yet, so this might not be the actual release date, but I think Gamestop is pretty reliable source. Second thing is that since the game has five episodes, this is only the release date for the first episode.
