Well, and there's the small fact that on the website they keep shoving the concept of Juliet being Shawn's love interest in everyone's faces... it's in quite a few videos. I could be wrong, but I think there's a specific question about it... Maggie Lawson and James Roday both seemed to have to answer of that sort.
I almost feel like they're stressing it so much there (on the website) that they're not going to do it, and are really just trying to make us think we know what is going on/going to happen.
But that's just me. I'm a conspiracy theorist.
