I'm not seeing Fantasy Flight listed anywhere in the exhibitors or tourney list, is there not going to be one this year?

There is Netrunner on the list. I guess FFG no longer need to promote X-wing at PAX.

X-wing is happening at PAX West this year, only in a more casual form than a set tournament. They are taking 8 man pods as people sign up throughout the weekend. Omega ace alt for participation and acrylic bigs card for winner of each pod after three rounds. Totally worth doing if you are at PAX West this year.
