Tonight James Hinchcliffe was the co-host on the "Wind Tunnel", and one of the guests was Sam Hornish, and Hinchcliffe basically asked Hornish why Allmendinger in Penske's 3rd car at the INDY 500, and not him, and Sam's answer was everytime I think I'm ready to go back to INDY Car something happens that changes my mind. Reading between the lines of Sam's answer I think if Wheldon doesn't get killed at Vegas Hornish would be back in INDY Car.
