Looking at Rod's website their events page lists:

http://www.lewisairlegends.com/events/

"09 11 13 - Reno National Championship Air Races and Air Show
Lewis Air Legends Planes to Attend: Rare Bear Air Racing and Lewis Air Racing teams will be present.
September 11-15, 2013
Reno, Nevada"

So for all you Bear faithfuls, that a good sign that they will bring Bear back. Especially when you look at other events and they say TBD.
