Unless something really unexpected happens, like an early invitation to confirm/configure, I think that I will be in the '09 production run, even with a 25 JUN reservation date. My dealer is planning on a through-put of 10-12 cars per month, and last time I spoke to someone they were looking at 250 "leads." Other figuring, including a guess on total attrition, sways me to think that I am 60% of the way into his list (IB/smartUSA's list for him). So, that looks like I'll rise to the top about the end of FEB '09.
Somewhere I read that there will be no major changes between '08 and '09, but hopefully the bugs will be worked out. For me, I will be mindful of a potential MSRP increase until such time as I C&C and they establish my price(s).
