Bigpoint has officially named the MMO based on the Game of Thrones book series. Called "Game of Thrones Seven Kingdoms", the team also announced that the first trailer from the game will be released at this year's ComiCon in San Diego.
In context of the lore, the Seven Kingdoms were originally independent countries which rose up over thousands of years until the Targaryens ruled over them as one nation of Westeros. Game of Thrones Seven Kingdoms begins after the deaths of King Robert Baratheon and Ned Stark. The Starks of the north declare war on the south and Baratheon’s two brothers both make claims to the throne. Players are challenged to form alliances through Player vs. Player (PvP), Siege combat and politics to control Westeros.
Beta testing is slated to begin later this year. Sign up on the official Game of Thrones: Seven Kingdoms site.
