Starting with multiple tweets from Jordan Maison, editor-in-chief at Cinelinx, who stated:

Though it can’t be confirmed, it is interesting to note Maison leaked info on a “Rogue One DLC” which turned out to be true. Further clues lie in the timeline before the release of the first Star Wars Battlefront.

The first installment was first revealed at the E3 expo on June 10, 2013 and the following E3 in 2014 showed another trailer for the game. By April the release date was announced as November 17, 2015 at Star Wars Celebration that year. The timeline of the upcoming sequel runs on a far expedited scale, but we can predict the similarities will be significant. The second installment was revealed in an investors call on January 31 of this year by CEO Andrew Wilson. Wilson stated in the call:

The news was the official statement by the CEO even though the first mention of a sequel by DICE occurred the previous November of 2016. This statement was from EA CFO Blake Jorgensen who revealed the release date to be around the same time, holiday of 2017. The final additions to the original game occurred this past December with release of the “Rogue One: Scarif” DLC in anticipation for the upcoming movie that month. This gave DICE 10 - 12 months of solid work on other projects and the upcoming game, save minor bug fixes and balancing in smaller updates to the game that have happened already.

So what does this mean for the new games’ timeline and Star Wars Celebration 2017 roughly two weeks away? On an escalated timescale we can assume a first look at the game’s trailer at celebration this year. This would be similar to Star Wars Celebration 2015 where the first game details but second game trailer were released. After that we can expect celebration to be another opportunity for questions to developers about the game, but no game play until EA Play in June taking the place of E3.

Furthermore, we will get to see the game devs talk about their work on the game and the difficulty it took to expand maps, development on the new heroes, and show pride in new weapons or systems without giving away too much. The final similarity we might see is the reveal of the official release date for the game if EA follows a similar path as before.

Star Wars Battlefront 2 will likely be released before Star Wars Episode VIII - The Last Jedi in December, which will have plenty of talk at celebration as well. This would be another similarity to what EA did with the last battlefront DLC release before Rogue One. Finally, if there are any DLC’s for this battlefront game like the last, at least the first will be revealed here as the first DLC for Star Wars Battlefront was shown at celebration in 2015.

Star Wars Celebration 2017 takes place April 13, with tickets on sale now. Expect the first Star Wars Battlefront 2 trailer and more news before EA Play.
