So, the order has gone:
4, 5, 6, 1, 2, 7, 3 ????
Why the hell do they do that crap?
Question, does the new episode take place after TFA or do they go back to an odd order of the story?
I really didn't like the two episodes that went back in time.
Woah, BRB. How much of Star Wars are you familiar with?
It started with 'Star Wars' (A New Hope). The original trilogy, from 1977 to 1983 (ish?) went in order. These became episodes 4-6 when George Lucas decided to do a prequel trilogy, which went 1-3 in order.
TFA continues 30-some years after Episode 6, and the new trilogy (7-8-9) will go in order.
Rogue One is part of a probably infinite series of disconnected offshoots from the main franchise, so it doesn't really matter where in the timeline any of them go.
Release Order: [4, 5, 6] - [1, 2, 3] - [7, 8, 9]
Chronological Order: [1, 2, 3] - [4, 5, 6] - [7, 8, 9]
As MC points out, Rogue One happens to be slotted chronologically in between the 3rd and 4th episodes because there's some gap to be filled there, but it's not part of the main series.
