As of now it looks like registration will be up January 1st.
Events planned that I know of so far... car show at Mesa Riverside, Firebird West and possibly Main road coarse, autocross at the Nissan test facility, opening and closing ceremonies in the Wild Horse Pass theater, rooms for $119 a night which includes around $30 a day in money kick backs for food and gambling... so around $89 a night... and the kickbacks can be accrued for use whenever you want, cruise to Payson/Sedona/Jerome, Friday Night Drag racing at Firebird, Pavilions car show... and so much more...
and don't let the heat scare you... it's a dry heat
