Snooki might change her mind in another year or two. She is just about at the end of the road with what she can do. Her show with Jwoww has just about run its course and even they can't stand to be next to each other too much any longer. Jwoww has promised to show up at DWTS if Snooki makes it through the first five episodes but isn't going out of her way to come any sooner.
What is someone like Snooki going to do in the future? A money paying gig even if it means reuniting with The Situation might be just what she has to do to make a buck.
