I think it's been Rachel all along. She's the only one I've seen any real mutual physical chemistry with Preston. Rebekah and Andrea threw themselves at him, but he wasn't responsive to them. If I thought that Preston was playing the game for money, then I would pick PJ. But he has always given Rachel the benefit of the doubt- siding with her when the other girls called her out, keeping her with the $1 check. So I say Preston picks Rachel, Rachel takes the check, becomes the star of FLOM4, and we resume this inane cycle all over again.
