I think we'll have to wait for this year's to air and see how well it does. I honestly believe, depending on how good/bad the coverage is seen by Joe Schmoe, that it could change the turnout by almost 1000 in either direction. My guess is 6,300-6,4000 for 2006, leveling off around 6,000 after that. I think it hits its peak in 2006, unless something really crazy happens (Hachem or Raymer make the final table, something along those lines).
