I am curious to see what the new coupe looks like. All these renderings are cool, but may not be close, we just don't know yet.
Historically, Alfa's coupes don't look anything like their sedan counterparts, but with the efforts at keeping down manufacturing costs, that may change this time. The cars may share some body panels. For me, the coupe will be pointless unless it offers a performance edge over the sedan. If it's lighter and or has a more rigid chassis, that's a plus. However if it's just a styling exercise, I'll pass.
