We've recently had many 'Gee, we haven't gone there in ages, let's go again' locations - Australia, Taiwan, Joburg and/or Nairobi, RDJ, St. Petersburg, etc. In addition, we've most recently hit central and Scandinavian Europe, and from history, 8 can say WRP doesn't hit the same geographic region in consecutive races (India and China excluded).
I think we might get a leg(s) on the Mediterranean. Greece is out, but maybe Italy or a Balkan state? Or an actual leg in Spain?
