The Press Tour for broadcast networks is being held the week Gilmore Girls goes back filming (which is the week of July 16-22 - well that's when they went back last season), so the panel would be held sometime during that week (depending on the date CW is presenting).

Last year WB President had to deflect all the questions being asked about the snubs, which of course Lauren, Amy and Co had to answer at the WB Party the same night so my guess is they'll attack the GG representatives at the Panel first and then the CW party that night.
