Many updates have been appearing on the web regarding on what fans and viewers may expect on the show's brand new season including the speculated story line and other notable actors to appear on the seventh season.

Just recently, HBO has released an official poster for "Game Of Thrones" season 7 which simply emphasized the upcoming war between Ice and Fire.

The series' main theme "A Song of Ice and Fire" will finally be seen.

The official teaser for "Game Of Thrones" season 7 has also been seen on social media and with the little details the video had, fans could only speculate about the incoming doom the characters have to face. War will surely be the biggest event for the upcoming season but the destruction of mankind will also be intense.
