Honda should match the 911 not the Lotus Esprit, as far as how much time goes between refreshes.
I think a super lightweight V6 with cutting edge styling is my first choice....(maybe because I'll bet that Honda won't develop a V8 for environmental, weight, and development costs).
I would love to see a lightweight V8, with a curb weight around 3000lbs. It would put the nsx in it's own class as a halo car, above the 911, and below true supercars (enzo, mclaren, etc.)....maybe being in it's own class doomed the original nsx as far as sales go...I don't mind, I would rather not see my car all over the place like 911's, vette's, f 360's.
