I wouldn't be surprised if they tiptoe around it. It's possible to have multiple continuities, it's something that happens a lot especially with games and novelizations.
My personal preference would be an amalgamation of all the possible playthrough outcomes to make something unique that you couldn't get playing the game (like what would happen in Dragon Age with origins you didn't take part in), I'd still like the particulars of the main character to be unspecified though, unless they let us do it ourselves in dialogue like Knights of the Old Republic II and The Witcher 3.
