In 12-leg seasons, non-eliminations seem to be common on Leg 5. Seasons 5, 7, 10, 11, and 14 had non-elims on Leg 5. So I'd say that is a good place to predict a non-elim. Plus it would be the first of two Pit Stops in one country, which makes it seem all the more likely that this would be the case.
Legs 4 and 6 are, historically, rarely non-elimination legs. Leg 4 was one in TAR6, but not since then. And Leg 6 was only a non-elim in seasons 1, 2, and 13. Thus I think that given this fact and the information we know about the route, I'd predict these won't be non-elimination legs.
