There will still be a formal announcement, probably in early January. Robb said they still need to have all the documents signed (State of Kansas, Unified Government of Wyandotte County, Cerner and Ongoal) and sell Star bonds (by March 1st).

Looking across approximately midfield towards Kansas Speedway...
