Just a little prediction about the format of the new episodes. Obviously there's rumours that 'Season 7' will only contain 7 episodes and 'Season 8' will contain just 6. However, I'm thinking that 'Season 7' will be the final season of the show and have a total of 14 episodes. These 14 episodes will be split over two years with 'Part 1' airing in 2017 and 'Part 2' airing in 2018. 'Part 1' will have 7 episodes and 'Part 2' will have 7 episodes (the showrunners said "down to the last 70-75 hours" so it's not 100% going to be 13 episodes remaining). One of the main reasons I think they'll do this is because the number 7 seems to be a recurring number in the show (Light of the Seven, Seven Kingdoms etc.) and it seems a good number to end it. Additionally, Breaking Bad aired it's final season in two parts so it's not unlikely.
Sorry if this seems really long-winded but I hope other people can share their thoughts on this!
