The raider is canon!! Another thing to gather from the trailer, is how much we see star fighters. This made me analyse the trailer further, and I think the story mode is mainly about space fights!
Let me explain. So the narration we have in the trailer is a woman talking, presumably the one in endor. After some detailed looking up, I've concluded they are TIE pilots, but with a red stripe on the helmet? THEY ARE A SPECIAL SQUADRON, another thing, is how they show the raider and it's escort of 2 TIE fighters... could it be a special ops team that needs a slim ship? And the most 2 important pieces of evidence: the central character with the game name is not any main or even extra iconinc figure like a normal stormtrooper, it's a TIE PILOT! And linking to this there is a symbol in the EA website, which seems to be in the TIE pilot helmet, reinforcing the idea of a special TIE squadron!!
Am I going crazy or it really seems that the campaign promissed for Battlefront II will be space focused? <3 I am loving 2017 star wars wise!
