Honda may or may not think so, but the V6 Accord coupe so does not feel like a Prelude nor does it drive like a Prelude. The closet Honda has is the S2000 but even then, totally different driving experience.
I know that without a roadster, if I dont need a sedan when it comes time to buy myself another car down the road..if they dont have the Prelude or a car like it I most likely won't be driving Honda any longer.
It's too soon to say what will or won't happen though, I say it comes back but it takes I read, 7 years to design a new car from the ground up and any Prelude would be totally new.
