Let's skip the speculation and go straight to the source, shall we?
From this article
"The November Nine will be encouraged to stick around the next day (July 15) for a photo shoot, but according to WSOP Communications Director Seth Palansky, "Nothing is mandatory." The Player Release Form for all Main Event entrants is the same form used in prior years, and the November Nine will have no additional responsibilities forced upon them. There are no "reality TV" scenarios, and if the players don't want any ESPN cameras following them home, that is their choice. "
I guess maybe they could film something that could be broadcast afterwards if they players wanted to be a part of it, but keep in mind too that there won't actually be a break in the televised schedule.
know that there's a four month break between the final nine being decided and the winner being crowned, Joe Public will be watching one episode a week in that time. So ESPN would have, at most, a week (in between the time when they televise the episode where they get down to the final nine, and when the final table is played) to use any "reality show" footage.
