Chevrolet is promising to break some Camaro news tonight at the Barrett-Jackson Auction in Scottsdale, Ariz., but the company isn't saying what.

It's unlikely that the news will be related to the upcoming Z28--although, who knows?--so we speculate that Chevrolet is likely to unveil something smaller, such as an appearance package for the Camaro Convertible. which launches very soon. The timing certainly would make sense.

Or maybe Chevrolet will unveil a NASCAR Camaro.

Whatever the case, tune in on the Speed Network at 8 p.m. EST/6 p.m. PST to find out.
