the Altima coupe sells well... the 350Z and G35 coupe sold well... the 370Z/G37coupe sell well... the Civic coupe sells well... the new Genesis coupe sells well... the Mustang sells well, even after being the only domestic rwd muscle car in production for 6 years...
the Camaro will do just fine... the "gotta have it factor" combined with the impressive new characteristics will keep it selling strong for quite a while... and the V6 getting 29mpg on the new highway mileage ratings will help, too
