Maybe Ozzy's "overexposure" is a reference to some of his other um video activities? Definitely not something Rupert has ever done!
I think our problem is one that was referred to above....that they had what, 25 guys, competing for 10 slots. The men have been a lot more memorable than the women it seems, both good and bad. If they want to have even numbers of men and women they've got a problem.
Re people from the older seasons...part of the problem there is also aging...it's been a while since that first season. Some people may literally be past Survivor's upper age limit (I assume they have one?), or have developed health problems, or actual careers they can't leave, while others whose main function was eye candy may not meet that standard any more....
I'd like the idea of a 2nd chance season for people felled by accidents (Skupin, for example) or very sneaky twists (e.g, Shi- Ann) or illnesses unlikely to reoccur. And then add some of the first boots....a lot of those though were the oldest member of their tribe, especially the women, so they may have aged or health problemed out by now. NO ONE who has had a 2nd chance already, much less a 3rd. As mentioned above, we often didn't get to know these people well, so it will be almost like a new cast.
