I told you I would be in the minority

My 09 has 20000 miles on it.
All these opinions are very valid.
I would suggest you test ride one. Maybe rent a new one for a weekend.
Riding style has a lot to do with it as well as your comfort level. Even where you live. I live in IL. were the roads are flat, straight, and bumpy.
If I want to hammer a turn I will throw a leg over my CRF450 and blast through a berm. Raced MX for over 20 years and participated in the evolution of the stiffer frame/better handling MX bikes. A stiffer frame will no doubt handle better, with the suspension tuned. The caveat to that is: the stiffer the frame the more important the suspension becomes. In the case of HD, and the new frame, the frame is better but the suspension.... well, you be the judge of that.
The Cadillac to sports car comparison is a great one.
My 09 CVO Ultra
is my Cadillac but it is not as soft a ride as my 08 ultra Caddy was. Point is you really don't get it all in one package. Most of these Ultras spend more time vertical on highways then they do draggin' knees and elbows in turns.
Like JCZ said I think some of the other new improvements will stand out to you also.
If you drive a new bike I think you will want one...I just don't think it will be all about the frame.
