It'd be great if they are. I wish there were a way to know for sure though. Actually, I know a certain someone who works for Nissan Corporate who might stand a chance of finding a definitive answer for us. I'll PM him and update this thread if and when I get a response.

Sweet! Light at the end of the tunnel. Thanks for the detective work! Tell him I asked in December and got no response.
