First the simple answer: If they have ten $25K winners, I expect that they will go back to the format of their first tournament.
As for last season, they had at least a few new shows in March and April, and in May they had Soap Hunks week (four brand-new shows) and Sweethearts week (two brand-new, one or two reruns and the other one or two were shows that had sat around without airing). They even had a few in June and one that sat around unaired until August 1.
I'm not positive, but I believe every $25,000 winner from last year was in a ToC. This year, they had five before the first ToC, so I assume there will be another ToC with that person in it.
