i was reading on another site where they interviewed the producer. He said this will go on until 2005. The viewers of the show of course will know who the killer is. But, there is a twist in May of this year. They asked if it will be sort of a Dallas dream, he said no, but it will have a twist, and he isnt going to reveal it. Interestingly enough, I read that Days has renewed for another few years.
Here's the site where they did the interview:http://www.soapsite.com/spoilers/dool.htm
