Ford will use the Mustang model, Dodge will use the Charger, Toyota plans to use Camry but may goto the Solara version of the Camry, and Chevy will continue with the Impala but could switch to the Camaro.
I thought there were questions about whether Mesi would ever fight again, as he suffered some brain bleeding in his fight against Jirov. Which is a shame, because he was fun to watch, even if not exactly the best fighter out there.
