Well, I'm not sure how much of a sign it is, but the classifieds might tell some of the story. Daron Clayton has his 2006 Beast for sale, which isn't too much of a shock.

However, in the ad it reads that trades accepted are new Maxim / J&J winged sprint car frames, new or slightly used. So, could this be the sign of Clayton going back to the winged sprint car ranks? I hope not...
