Here is the scheduling order.  Apparently lawyers at Arnold and Porter have time on their hands and the ACLU has money to waste.  This will likely not turn out favorably for the plaintiffs.  From the Arnold and Porter website:

In addition to David Gersch, the Arnold & Porter LLP legal team included Michael Rubin, Dorian Hurley, Rosie Smith, Dana Peterson, Stanton Jones, Whitney Moore, Joseph Schlingbaum, Dan Bernstein, Rachel Frankel, Dawn Yamane Hewett, Bassel Korkor, Marissa Styne, Susan Rabinowitz, Christine Lao, Cathy Hoffman, John Freedman, Donna Patterson, Mark Colley and Kelby Ballena.
