Speculation Topic (no spoilers)
I suppose there's lots we could speculate on... but to start, in the pre-race interview clips on CBS.com Erika the naked Skydiver and Dennis, the naked-Sykdiver watcher, mention that they planned to come on the show with a strategy to be the mean, manipulative ones but due to "the rule changes" they are rethinking their approach.
What could they possibly mean?
Assuming you have hard info, I'd hope a spoiler tag or two could be used. :) Otherwise, I think it would be fun just to speculate.
