I'm not sure where you heard that Hyundai will be producing the Sonata as a coupe? According to John Krafcik, the coupes in Hyundai's stable so far are the Gen Coupe and the soon to be released Veloster. That "shopped" image has been making the rounds for the last 6 months or so now.

Its fun though to speculate but this is least likeliest to happen as in less than zero chance.
