There are a LOT of scheduled events, so no way to know if they'll be at this one, but FWIW, BGG is livestreaming from GAMA tomorrow:

...might be worth following, if nobody else shows up with a stream more specifically FFG focused.
They'll be there. X-Wing is one of the most popular games of the last several years, there's no way they'd miss a chance to report on big news for probably the most popular games they feature.
