They made a mention of it on their OP Twitter account yesterday:
It looks like they are talking about the panel for Organized Play specifically, which is today at 5:00 pm. It won't be an announcement of new ships, but it could be interesting. Regardless, the big show is still tomorrow at 11:00 am.
Unless they introduce some sort of mission based tournaments or story driven organized events, I really don't care about Organized Play. It's just like the latest thing about all these events around the world.....it has nothing to do with me or how I play X-wing.
Hope it's something more than just OP announcement.
He meant that tweet was specifically about the OP panel, which it likely was since it was tweeted by FFGOP and specifically said it was OP announcements. There hasn't been a similar tweet from the regular FFG account giving any kind of hint as to what today's panel will be about, other than it's Asmodee doing "FFG and Star Wars."
