I just looked at the schedule for map reprints. It looks like there aren't any more TransAm updates happening until mid-2010. However, I'd wait a bit on purchasing a set since not all of this year's updates are available for sale and you're not leaving for several months. John was correct in stating that we usually sell out of existing stock before bringing in the newest printing. I don't know the number sales has in stock at the moment but check back in a few months to see what the status is. You can contact me directly if you'd like.
