maybe they want to make a more affordable sports car. One that's not handbuilt and not so exotic. maybe 300-330hp v6 that weighs less than about 3400lbs. Hopefully it would still be rwd. However, I dont know how affordable it would be unless they were to use the platform on other products. Now platform sharing on a car like the nsx would be blasphemy to loyalists. Also making it more affordable would hurt the image of the nsx. So whenever they decide to bring it back, they will probably keep it as exclusive as it is now. And in the mean time they want a car that can make them some money.
Of course I'm probably dreamin. Afterall if they were going to make a rwd platform that can be used in several applications, they would've probably put the upcoming RL on that platform.
