(yes, yes, phrasing.)
We all know that FFG loves to recycle their art assets. Artwork used for X-Wing frequently makes it into the card game and Imperial Assault, and vice versa.
And now IA has gained the services of a Jedi hermit. Obi-Wan is now the only canon character from TV or the films who is available in that game, but not in X-Wing.
I think this makes his arrival within the game of X-Wing into an inevitability.
