As far as I know, most, if not all, of the NorCal MB scene (i.e. San Jose) have stuff to do on Saturday, so they won't be making it. However, I don't know the situation with the Guilty Gear players, but from what I gather by reading on Dustloop, the turnout with those guys won't be very high either.
I was planning on going if it looked like it would have a decent turnout, but now I'm kinda on the fence, leaning towards not going.
