FYI - Just an update on this topic.
I got the latest (Jan/Feb) N-Scale Collector magazine today and they've updated the ad.
Two major changes:
First, the last car now shows the USS West Virginia instead of the USS Utah (although the ad text still says Utah).
Second, they are using a different sillouette for each class (Arizona, California/Tennessee, Maryland/West Virginia, Nevada/Oklahoma).
So it looks like somebody is listening to the complaints.
Pre-order dates are listed as 28 Feb-30 March, so I'd expect to see these announced in March listing.
