I don't think you can have another Wendy and they'd be stupid to try. Wendy was so oddly...Wendy. She wasn't just a villain, she was very unique. I think they know how popular the Top 3 (Top 3, not Final 3) were (Kara Saun, Jay, and Austin) because of things like Austin's tribute and such. They have to know from what they've seen on the website that they had a good thing going with those people and will probably look for the same eclectic group again.
