Apparently the new style cards will use other titles if in your profile since my wife's Silver card arrived yesterday with her listed as Dr. Portolan which is correct. The Silver card has the Grand Wailea resort pictured on it. It says "Silver" in small text in the lower right and has a silver banner across the bottom so it may be that your status can be determined without the desk clerks having to remeber what resort = each status.

It'll be a year (at least) before I see the new Diamond card since my current card expires in 2012.
