I suspect that the answer is that their "standard" map takes some time to prepare. While certainly done on a computer, they require some effort to identify each port, arc the routes to avoid land masses, etc. The interactive maps are a small Google maps script that could actually be generated directly off of the itinerary listing.

I bet the old style maps show up as they get the 2009 cruises fully up to speed.
