Product placement has been an integral part of the Challenges in S2. It seems very likely that we will see more during this episode. The satelite dish (Cingular) has been identified in the vidcaps and makes sense as part the RC or its reward.
Another theory (discucced on the SS board) about one of the challenges makes reference to the challengers being "on target". It was further speculated that an "archery" or "dart board" challenge could actually be the RC with Shackles and Chains" being the IC. Could it be that the RC involves some kind of target shooting and the "bullseye" is the "Target" logo of one of the other sponsors?
Most on the SS Board seem be convinced that the IC is S&Cs and that the RC is something else (possibly the target shooting).
Maybe tomorrow morning we'll get a few more clues, but for now the spoiler boards seem to have very different ideas, it makes me a little nervous...
