Max, I haven't heard any word on when (or if, for that matter) there'll be the Shootout in 2010. I would be very surprised and disappointed if there isn't one -- but the nature of the event, including high costs per entrant, make it such that Mike might take his time to be sure of what and who will show up before he sets a firm date. Perhaps Mike Jr. will see this thread and comment.
However -- I believe the Shootout is "usually" the week right after World of Speed -- putting the Shootout in mid-September. If you want Mike's phone number -- PM me.
