Curious if anything has been changed except for the roadster option?

 

no news about it yet. rumors we have are the 3rd silver, or atleast another silver, could replace a current one, who knows.

not much detail out there yet.

from current info and judging by the fact that it would be coming out shortly and the convertable interior is same as current, Im gonna say no noticable differences.

 

Probably not. I'm guessing the new models will just have most of production line kinks iron'ed out.

I think it took Nissan 2 years to decide it worthwhile to "upgrade" the Altima's interior. I think it'll probably be the 3rd gen 350Z where we start seeing little things changed.
